<!-- Chaitanya Dairy PWA — ADMIN HAMBURGER MENU 25.7 (v25.7) — June 17, 2026, evening IST (approx — time tool unavailable) — 🟢 FIX: Tapping 👥 Customers under a specific route now shows ONLY that route's customers with the "All Customers" dropdown HIDDEN (locked to that route) — just the search box stays, exactly as requested. The dropdown re-appears automatically the moment the normal bottom "Customers" tab is tapped (full all-routes view again) or "← Back" is tapped from the ☰ menu. Stats remains its OWN separate row (unchanged, NOT merged into Dashboard — confirmed still correct from v25.5/25.6). Dashboard still opens directly with no sub-list (v25.6, unchanged). No money/billing/sync/Firebase changed. =====
PREVIOUS: Chaitanya Dairy PWA — ADMIN HAMBURGER MENU 25.6 (v25.6) — June 17, 2026, evening IST (approx) — 🟢 FIX: Dashboard no longer expands to a sub-list — tapping it opens the full dashboard directly (calendar, Agent Location, Quantity Alert, Notifications, Mark Deliveries, Tomorrow's Orders together; Stats excluded, has its own row). =====
PREVIOUS: Chaitanya Dairy PWA — ADMIN HAMBURGER MENU 25.5 (v25.5) — June 17, 2026, evening IST (approx) — 🟢 NEW ☰ HAMBURGER MENU (Phase 2), opens from LEFT, separate from ⋮ (RIGHT). Routes → Dashboard(sub-list)/Stats/Route/Bills/Customers. Stats = dedicated calendar view. Bills/Customers pre-filtered + customer counts added to Bills/Customers pages. =====
PREVIOUS: Chaitanya Dairy PWA — ADMIN DOTS MENU 25.4 (v25.4) — June 17, 2026, evening IST (approx) — 🟢 ⋮ MENU REDESIGN (matches Kavitha's screenshot). Flat list of routes + Exit at bottom, no collapsing. Tapping a route opens that route's COMPLETE dashboard full-screen. Advance Orders + Summary HIDDEN (not deleted) in this view only. Drawer opens from RIGHT, narrower (v25.2). =====
PREVIOUS: Chaitanya Dairy PWA — ADMIN DOTS MENU 25.3 (v25.3) — June 17, 2026, evening IST (approx) — 🟢 ⋮ MENU: MARK DELIVERIES opened calendar + agent location + list + search together. (Superseded by v25.4 flat-list redesign.) =====
PREVIOUS: Chaitanya Dairy PWA — ADMIN DOTS MENU 25.2 (v25.2) — June 17, 2026, evening IST (approx) — 🟢 THREE SMALL FIXES: (1) HEADER ORDER Admin name → 🔄 Refresh → ⋮ Menu (⋮ far right). (2) DRAWER OPENS FROM THE RIGHT (was left). (3) DRAWER NARROWER (64%/270px). Exit at bottom of drawer; header Exit hidden for admin. =====
PREVIOUS: Chaitanya Dairy PWA — ADMIN DOTS MENU 25.2 (v25.2) — June 17, 2026, evening IST (approx) — 🟢 THREE SMALL FIXES: (1) HEADER ORDER Admin name → 🔄 Refresh → ⋮ Menu (⋮ far right). (2) DRAWER OPENS FROM THE RIGHT (was left). (3) DRAWER NARROWER (64%/270px). Exit at bottom of drawer; header Exit hidden for admin. =====
PREVIOUS: Chaitanya Dairy PWA — ADMIN DOTS MENU 25.1 (v25.1) — June 17, 2026, evening IST (approx) — 🟢 TWO FIXES to v25: (1) ⋮ MENU WAS EMPTY — buildMenu filtered routes by a.active, but routes don't have active=true set. FIXED: ⋮ menu now lists ALL routes like the route tabs. (2) EXIT MOVED INTO ⋮ MENU — header Exit hidden for admin; 🚪 Exit at the bottom of the drawer. Nothing else changed from v25. =====
PREVIOUS: Chaitanya Dairy PWA — ADMIN DOTS MENU 25 (v25) — June 17, 2026, evening IST (approx) — 🟢 ADMIN ⋮ MENU — PHASE 1 (organizes the long-scroll Today page). Added a ⋮ button (top-right, blue) shown ONLY for admin. Tapping it opens a drawer listing each route as a collapsible header (🚴 Route name ▼); tapping a route expands to show 5 items: 📍 Agent Location, 🟣 Purple Alerts, 🔔 Notifications, ✅ Mark Deliveries, 📋 Tomorrow Special Orders. Tapping an item switches to that route and opens THAT ONE section full-screen with a "← Back to Today" button. Today/Stats/Summary tables UNCHANGED and stay on the main Today page. No calendar — same-day info only. Reuses existing elements (dashLiveTrack, qtyChangesCard, notifBar, markDelivCard, tomorrowOrders) + their v21.9 accordions — nothing duplicated/deleted. Phase 2 (later): ☰ for Bills, Customers, Advance Orders, Settings. No money/billing/sync/Firebase changed. Agent ☰ and customer ☰ menus unchanged. =====
PREVIOUS: Chaitanya Dairy PWA — AGENT MENU 24.10 (v24.10) — June 17, 2026 — 🟢 FIX: Stats (and Contact) were briefly/again appearing on the agent main Route page. Root cause: renderRoute force-set routeStats and callMgrSec to display:block on every render, overriding the ☰ menu hide. FIX: for agent, renderRoute no longer forces these visible — the ☰ drawer fully controls them (showSection shows the picked one with display:block, showHome hides all). Admin view unchanged. Nothing else changed from v24.9. Display only. =====
PREVIOUS: Chaitanya Dairy PWA — AGENT MENU 24.9 (v24.9) — June 17, 2026 — 🟢 AGENT HAMBURGER MENU + CARD ⋮ MENU. (1) Added a ☰ menu button (top-left, green) shown ONLY for the delivery agent. The agent Route page now keeps the delivery customer list (with purple ribbons + landmark — UNCHANGED) plus date, note, and location on the main screen. Four sections moved into the ☰ drawer: 🔔 Notifications, 📊 Stats, 📋 Tomorrow Orders, 📞 Contact Manager. Tapping a menu item opens that section alone with a "← Back to Route" button. Purple ribbons stay on each customer card (NOT moved) so the agent sees order changes while delivering. (2) Each customer card now has a ⋮ three-dots button → 📞 Call Manager (calls owner/manager number only — agent never sees customer phone numbers). Display only — no money/billing/sync/Firebase listeners changed. Admin view unaffected (☰ hidden for admin). ===== PREVIOUS: Chaitanya Dairy PWA — MENU 24.8 (v24.8) — June 17, 2026 — 🟢 COLOR TWEAK: Customer 🚴 Delivery Status box changed from thick dark blue to a soft pastel blue (#E9F2FC→#D6E8F8) with dark blue text and a light border — easier on the eyes. Nothing else changed from v24.7 (hamburger menu intact). Display only — no money/billing/sync/Firebase changed. ===== PREVIOUS: Chaitanya Dairy PWA — MENU 24.7 (v24.7) — June 17, 2026 — 🟢 CUSTOMER HAMBURGER MENU. Added a ☰ menu button at the TOP-LEFT of the customer header. The customer home screen now shows ONLY: Today's Delivery, Delivery Status, 📞 Call Manager, and 🛒 Order More. The other five sections (🥛 Milk Settings, 📊 Monthly Details, 💰 My Bill, 🏖️ Vacation Hold, 📍 My Address) are hidden from the home screen and moved into the ☰ slide-out drawer (opens from left, shows customer name on top). Tapping a menu item closes the drawer and opens THAT section alone as a focused screen (everything else hidden), with a "← Back to Home" button at the top to return. Resets to home on every login/return. 🛒 Order More always stays on the home screen for easy ordering; Call Manager always visible for emergencies. Display only — no money/billing/sync/Firebase listeners changed. ===== PREVIOUS: Chaitanya Dairy PWA — LOGIN CHANGE 24.6 (v24.6) — June 17, 2026, ~1:30 PM IST (approx — time tool unavailable) — 🟢 PIN SCREEN NOW SHOWS YOUR ACTUAL NAME. Previously the Admin PIN screen always said generic "👤 Admin Login" regardless of whose phone number matched — even after renaming yourself/Vardhan in Settings → Admin PINs → Rename. Now it captures WHICH owner's phone matched and shows "👤 [Their Name] Login" (e.g. "👤 Kavitha Login"), same idea as how the Agent screen already shows the agent's real name. Using the safety-net "Login with PIN instead" link still shows generic "Admin Login" (since no specific phone was matched there) — that's expected. No data/billing/sync/Firebase changes — display only. ===== Chaitanya Dairy PWA — LOGIN CHANGE 24.5 (v24.5) — June 17, 2026, ~1:10 PM IST (approx — time tool unavailable) — 🔴 CRITICAL DATA-SAFETY FIX: owner/agent phone numbers could get silently WIPED across all devices. Root cause: when syncAuthData()/syncAll() pulled owner or agent data from the cloud, if the cloud copy was ever missing the phone field (e.g. one earlier failed save), the merge logic would overwrite a device's correct LOCAL phone with the cloud's blank one — and since syncs run automatically and often, this could erase a working phone number even after you'd successfully saved it. FIX: merge logic now ALWAYS keeps whichever of local/cloud has a non-empty phone (and for agents: agentPhone + active flag too) — cloud data can never again silently erase a good local phone number. Applied to all 3 merge locations (syncAuthData, syncAll, post-login resync). ACTION NEEDED: Re-save your phone (Settings → Admin PINs → Set Phone) and Vardhan's phone once more, so the cloud copy gets refreshed cleanly under this safer logic — going forward this should hold permanently on all devices including Incognito. No billing/sync-listener/Firebase structure changes. ===== Chaitanya Dairy PWA — LOGIN CHANGE 24.4 (v24.4) — June 17, 2026, 12:53 PM IST — 🔴 CRITICAL FIX: doPhoneLogin was checking "settings.routes" but the real field is "settings.agents" — a typo that made the agent list ALWAYS EMPTY, so agent phone login could never succeed no matter what else was fixed in v24.1–24.3. Fixed to settings.agents. ALSO FIXED: doPhoneLogin now calls syncAuthData() FIRST (pulls fresh owner/agent/customer data from the cloud) before checking the phone number, so login works correctly even on a phone/browser that hasn't synced this number locally before (e.g. testing on a different device than the one used to save the number). Button shows "🔄 Checking..." briefly during this. No billing/sync-listener/Firebase structure changes. ===== Chaitanya Dairy PWA — LOGIN CHANGE 24.3 (v24.3) — June 17, 2026, 12:14 PM IST — 🟡 FIXES AGENT LOGIN BUG + NUMERIC-ONLY PHONE BOX. ROOT CAUSE found: when an Agent's PIN is set, the route's "active" flag was never set true (only Owner PIN-setup did this) — so the v24 phone-login agent check (which required active=true) silently failed even with correct phone saved. FIX 1: Agent PIN setup now also sets agents[i].active=true, matching Owner behavior. FIX 2 (safety): doPhoneLogin's agent match now accepts EITHER active=true OR an existing pinHash as proof of being a real configured agent — so any agent whose PIN was set before this patch also works immediately, no need to re-set PIN. FIX 3: "⌨️ Type Number Manually" for agent phone is no longer a popup prompt — it's now an inline box with a real number input (digits only, auto-capped at 10, numeric keypad) + a Save button, so typing is restricted to 10 digits as it happens, not just validated after. No billing/sync/Firebase changes. ===== Chaitanya Dairy PWA — LOGIN CHANGE 24.2 (v24.2) — June 17, 2026 — 🟢 ADDED MANUAL PHONE ENTRY FOR AGENT. Settings → Agent route card previously had ONLY "📱 Pick Agent from Contacts" (Contact Picker API) — no way to type the number by hand if the agent isn't saved as a phone contact. Added a new "⌨️ Type Number Manually" button right below it — opens a simple prompt to type/edit the 10-digit number directly, same validation as owner phone (Set Phone). Both buttons now sit side by side; use whichever is convenient. No data structure change — still writes to the same agents[i].agentPhone field. No billing/sync/Firebase changes. ===== Chaitanya Dairy PWA — LOGIN CHANGE 24.1 (v24.1) — June 17, 2026 — 🟡 FIXES v24 LOCKOUT BUG: DB.owners never had a phone field (only settings.ownerPhone existed, a single "Manager Phone" used elsewhere) — so owner phone matching in v24 always failed. FIX: (1) Added phone field to DB.owners[] (additive, backward-compatible — old saved owners just get phone:'' until set). (2) Settings → Admin PINs → each owner card now has a "📱 Set Phone" button to register Kavitha's and Vardhan's numbers. (3) doPhoneLogin now checks owners[].phone correctly (plus settings.ownerPhone as extra fallback). (4) PERMANENT SAFETY NET: login screen now always shows a small "Admin / Agent? Login with PIN instead" link — tapping reveals Admin/Agent buttons that go straight to PIN entry, bypassing phone lookup entirely. This means Admin/Agent can NEVER be locked out again even if phone numbers are wrong/unset. ACTION NEEDED: Settings → Admin PINs → tap "📱 Set Phone" for both Admin and Proprietor, enter Kavitha's and Vardhan's numbers. No billing/sync/Firebase listener changes. ===== Chaitanya Dairy PWA — BILL 24 (v24) — June 17, 2026, 7:12 AM IST — 🟢 LOGIN REDESIGN: Single phone-number login screen. No more 3 separate buttons. User enters 10-digit mobile → app checks: owner phone → PIN → Admin screen; agent phone → PIN → Agent screen; customer phone → Customer screen (stays logged in); unknown → "Not registered". Customer session saved in localStorage (auto-login on return). Owner phones stored in DB.owners[].phone; agent phones in DB.settings.routes[].agentPhone (already existed). No Firebase structure changed, no sync touched, no billing touched. ===== PREVIOUS: BILL 23.11 (v23.11) — June 16, 2026, 1:30 PM IST — 🟢 DISPLAY: (1) ➕ ADD PRODUCT TO HANDOVER. The handover box area now has a "➕ Add product to handover" button. Tapping it opens an inline picker: select the product from a dropdown (shows products not already in boxes), enter qty, tap ✅ Add → a new box appears for that product AND a new column appears in the Stats table (Handover = typed qty, To Deliver = 0 since no orders, Undelivered = typed qty). Works for any product including stock the agent carries without any customer ordering it. On Save, the product is stored in the handover map and extra pids are cleared. On Clear, the picker and extra pids are reset. (2) COLOR SWAP: Handover row values = pink (#E91E8C), Undelivered row values = red (#C0392B). Red = must return. All other colors unchanged. No money/billing/Firebase listeners changed. ===== PREVIOUS: BILL 23.10 (v23.10) — June 16, 2026, 1:05 PM IST — 🟢 DISPLAY: (1) DYNAMIC HANDOVER BOXES: The Handover entry area now shows one input box per product column — not just Cow + Buf, but also Ghee, Paneer and any active product that has orders today. Boxes auto-fill with ordered qty (or saved handover if previously saved). No more static Cow/Buf only. Storage upgraded to per-product JSON map (handover_v2_{date}_{routeId}). Backward-compatible: reads old _cow_/_buf_ keys if no v2 key exists. Save reads all boxes and writes the map; Clear wipes the map and boxes refill with ordered qty. Summary table combines all routes' maps. (2) VALUE COLORS IN STATS TABLE: Handover values = red, To Deliver = blue, Delivered = green, Undelivered = pink (#E91E8C). Labels and values now same color per row. No money/billing/Firebase listeners changed. ===== PREVIOUS: BILL 23.9 (v23.9) — June 16, 2026, 12:46 PM IST — 🟢 DISPLAY: (1) HANDOVER BOXES PRE-FILL WITH ORDERED QTY. When no handover is saved for a route, the 🐄 Cow / 🐃 Buf input boxes now pre-fill with that route's ordered quantities (instead of blank 0), so the default shown matches the table. After tapping ✖️ Clear, the boxes auto-refill with the ordered quantities too. (Added orderedCowBuf() helper using the same cow/buf split as the table.) (2) ADVANCE ORDERS IS NOW A COLLAPSIBLE SECTION ("📋 Advance Orders" pill) like the other dashboard sections — it no longer stays permanently open. Removed its old inner card box/title so the items read as a clean list inside the pill. No money/sync/Firebase changed. ===== PREVIOUS: BILL 23.8 (v23.8) — June 16, 2026, 12:34 PM IST — 🟢 DISPLAY (BUGFIX): HANDOVER/STATS NOW READS THE COW/BUF SPLIT CORRECTLY. The table's qtyFor used to read only a customer's single total attributed to their primary milk type, so a "both" customer (e.g. default 1L cow + 1.5L buf) came out as 0 / 0, and clearing the typed handover fell back to that same 0 / 0. Fixed: qtyFor now uses the customer's cowQty/bufQty day-split when present, then a legacy single-type day override, then getCustDefaults (cowDefault/bufDefault — which understands cow/buffalo/both + cowLitres/bufLitres). So the Handover row auto-fills with the real ordered quantities (1 / 1.5), Clear reverts to those, and Delivered/To Deliver/Undelivered follow. Applies to all handover/stats tables (admin Stats, Summary, route page, agent). Read-only — no data written, no money/sync/Firebase changed. ===== PREVIOUS: BILL 23.7 (v23.7) — June 16, 2026, 12:24 PM IST — 🟢 DISPLAY: "🚩 No Route" TAB + EXTRAS FIX. Root cause of "extra shows in Summary but not Stats": Summary lists ALL customers, but a per-route Stats tab only lists customers whose route matches that tab — so any customer with a blank route OR a stale/removed route id was invisible in every route tab while still counting in Summary. FIX: (1) a "🚩 No Route" tab now appears next to the route tabs whenever such customers exist; tapping it shows their Stats (milk + extras), so nothing is missing from the per-route view. It catches BOTH blank-route and unknown-route-id customers. (2) Adding or editing an order now refreshes the dashboard Stats table immediately (previously only the advance-orders panel refreshed). No money/billing/sync listeners changed. ===== PREVIOUS: BILL 23.6 (v23.6) — June 16, 2026, 12:10 PM IST — 🟡 (minor) HANDOVER CLEAR: added a "✖️ Clear" button next to "💾 Save" in the admin Stats handover box. Tapping it (with confirm) wipes the typed Cow/Buf loaded litres for the SELECTED route (localStorage + handover doc set to 0, same mechanism as Save) and re-renders, so the Handover column automatically falls back to the ordered quantity. Per route, admin only. No money/orders/billing touched; no syncAll or Firebase listeners changed. ===== PREVIOUS: BILL 23.5 (v23.5) — June 16, 2026, 12:02 PM IST — 🟢 DISPLAY: AGENT VIEW = ONE TABLE ONLY. On the delivery agent's Route page he now sees exactly ONE "📊 Stats — <his route>" table (same columns/rows as admin, Cow+Buf always shown). The old 🥛 Milk Handover strip (circle grid + handover typing box) is now ALWAYS hidden for the agent, and he never sees any all-routes total / summary. Admin's own route view is unchanged (still 📦 Handover Tables = TOTAL + per route). No money/sync/Firebase changed. ===== PREVIOUS: BILL 23.4 (v23.4) — June 16, 2026, 11:48 AM IST — 🟢 DISPLAY: TABLE COLUMNS RULE. 🐄 Cow Milk + 🐃 Buffalo Milk are now ALWAYS shown as columns in both the Stats and Summary tables (even on a day with 0 orders, showing 0/—). All other products (Cow/Buffalo Ghee, Paneer, Curd, and any NEW product added later) stay hidden until they have orders, then auto-attach as a new column. Applies everywhere buildHandoverTableHTML is used. No money/sync/Firebase changed. ===== PREVIOUS: BILL 23.3 (v23.3) — June 16, 2026, 11:36 AM IST — 🟢 DISPLAY: ADMIN DASHBOARD = TWO TABLES ONLY. Removed the duplicate stat circles AND the second clashing "Handover". The Dashboard now shows exactly: (1) "📊 Stats — <route name>" = the SELECTED route only; columns auto-fill from orders + delivery ticks (Handover / To Deliver / Delivered / Undelivered); PLUS the optional 📥 Handover box to type litres loaded. The Handover row shows your typed/loaded number, with the ordered total in small grey underneath ONLY if they differ; if nothing is typed it auto-shows the ordered total. To Deliver = ordered − delivered. Undelivered = loaded − delivered (so any extra milk you loaded shows up). (2) "📊 Summary — All Routes" = the SAME table auto-totalled across ALL routes/agents, read-only (no typing box). The Route page handover strips were left untouched. No money formula, no sync, no Firebase listeners changed. ===== PREVIOUS: BILL 23.2 (v23.2) — June 15, 2026, 8:40 PM IST — 🟡 DATA: ALTERNATE DAY DELIVERY + BILL 23.1 ADMIN TEMP QTY — 🟡 DATA: ADMIN TEMP QTY in Edit Customer. A new purple "📅 Temporary Qty (Some Days)" section is added inside the admin Edit Customer modal. Admin can set a different milk quantity for a customer for up to 14 days (e.g. 1.5L instead of 1L from 16 Jun to 18 Jun) — uses the same periodQty system as the customer's own SOME DAYS option. Customer sees it in their own Milk Settings screen automatically. Agent sees it on the route card. A "✕ Clear Temporary Change" button is shown if a temp change is already set. If dates are left empty, existing temp change is preserved. Conflict guard (guardRangeVsVacation) fires if dates overlap with a vacation. 🟢 display changes from v22.3–22.5 fully preserved. ===== BILL 23 (v23) — June 15, 2026, 7:25 PM IST — 🟡 VACATION ↔ ORDER CONFLICT GUARD (a delivery and a vacation can never be on the same day). Works BOTH directions, in BOTH admin and customer windows. (A) When an order/quantity is placed for a customer on a day they are already on vacation (admin Add Order, admin Edit Order, customer single-day order, customer period qty-change) → a confirm popup appears: OK cancels the vacation and places the order, Cancel keeps the vacation and the order is NOT placed. (B) When a vacation is set over days that already have special orders (admin Edit Customer hold, customer Set Vacation Hold) → a confirm popup lists those days: OK sets the vacation and REMOVES those orders, Cancel keeps the orders and the vacation is NOT set. Note: a plain PERMANENT (onwards) quantity change is NOT treated as a conflict — only specific-day orders are. No money formula, no sync/Firebase listeners changed. ===== BILL 22.5 (v22.5) — June 15, 2026, 6:55 PM IST — ADDS TO FOCUS MODE: while a customer card is open, the search box and the route filter dropdown are now greyed out (dimmed) and disabled, so they can't be used until you tap that same customer again to close it. They return to normal (active, clickable) the moment you collapse back to the full list. 🟢 DISPLAY ONLY — no money/data/sync/Firebase touched. ===== BILL 22.4 (v22.4) — June 15, 2026, 6:47 PM IST — REFINES v22.3 FOCUS MODE: when you tap a customer card open, the page now auto-scrolls so THAT CUSTOMER snaps to the top of the screen (just under the blue app header) — so the customer's bill is the FIRST thing you see, with no scrolling needed. The month selector / search / route tabs / totals are scrolled above and remain reachable by scrolling up. Other customers stay hidden until you tap the same card again. 🟢 DISPLAY ONLY — no money/data/sync/Firebase touched. ===== BILL 22.3 (v22.3) — June 15, 2026, 6:37 PM IST — ADMIN BILL "FOCUS MODE": in the admin Bill tab, tapping a customer card now opens ONLY that customer and fills the screen — all other customer cards AND the footer total are hidden until you tap that same card again to collapse back to the full list. Only ONE customer can be open at a time (opening one auto-closes any other). Opening scrolls to the top so the bill starts cleanly; collapsing brings that customer back into view in the list. Fixes the confusion of accidentally reading the top customer's bill instead of the one you opened. 🟢 DISPLAY ONLY — no money/data/sync/Firebase listeners touched. ===== BILL 22.2 (v22.2) — June 15, 2026, 6:25 PM IST — (1) HARD GUARD against admin window showing to a customer (the intermittent two-screen stacking): showScr now forces a logged-in customer to ONLY the customer screen (any attempt to show the admin main screen is redirected to 'sc'); showPg no-ops for customer; renderBill no-ops unless admin. So even if a stray sync/listener fires, the admin bill can never appear over the customer window. (2) Customer "Advance payment" line restyled to "(Advance payment: ₹X)" — in brackets, slightly smaller (11px), light grey — so it reads as a soft detail, clearly NOT part of "You already paid". 🟢 display/guard. ===== BILL 22.1 — login flash fixes. BILL 22 — money single-count + login session clear. ===== PREVIOUS v20 — June 14, 2026, 6:36 PM IST — ADMIN BILL CARRY-OVER (running account): leftover/unpaid balance now carries to next month; overpayment becomes credit. Running ledger = sum of each month net (milk+extras owed minus marks/manual/advance), un-clamped. Card top circle = total due across months (carryIn + this month); shows Balance due / Cleared / Credit(adv). Card body shows Previous months due / Credit from before line when carryIn != 0. billDueForG/Pay-full/overpay-warning now use full carried balance. Per-month payment data unchanged & still synced via paid collection. NO Firebase listeners changed. Security rules unchanged. Customer window carry-over = NEXT step. -->
