# TechTitans POS — Customer CRM Phase C5 Layout Redesign

**Date:** 2026-11-12 · **Branch:** `techtitans/integration` (frontend + backend-docs) · Local commits only (no push/deploy).
**Builds on:** C2 (search/phone/duplicates), C3 (premium profile + human reference), C4 (finance overview). This is a **layout/information-hierarchy redesign** — a meaningful rearrangement of existing content, not a colour tweak. **No backend logic changed** (no confirmed defect found); all CRM features, calculations and APIs are preserved. No NH POS / legacy PHP / customer data touched; nothing pushed.

## 1. Old (C4) vs new (C5) layout

| Area | C4 (before) | C5 (now) |
|---|---|---|
| Header | **large navy→teal gradient banner** (tall, decorative) | **compact white identity card** — avatar, name, CUST- reference chip, type/status, phone·email·since, Edit + New sale. Teal left accent, navy type. |
| Tabs | pill tabs | unchanged six pill tabs (Overview/Sales/Repairs/IPTV/Appointments/Activity) |
| Summary cards | mixed count/due-total on each card | **four clean cards**: Total Sales (gross $), Repairs (open/total), IPTV (active/total), Outstanding Balance ($) — gross and outstanding kept on **separate** cards; larger values. |
| Actions | Quick-actions card + Edit duplicated in header *and* overview | **one compact action bar** (New sale/repair/IPTV, Add note, Add family, Group); **Edit appears once** (header). |
| Main layout | single left column (info + quick actions + family) with activity on the right | **balanced two columns** — LEFT **Financial overview**, RIGHT **Customer details** (+ recent milestones + family/groups). |
| Finance | **six tiny boxes + cramped chart** | **3 prominent figures** (Total billed / paid / outstanding) + a **service breakdown table** (POS vs IPTV vs Repairs n/a) + a cleaner contribution chart. |
| Recent activity | right column, 6 items | **moved below the two columns**, compact 2-up grid, latest 6 + View all. |

## 2. Design decisions
- **Compact white header** (§2) replaces the decorative gradient to reclaim vertical space; navy typography with a teal accent bar and a teal reference chip keeps it premium but quiet.
- **Four summary cards** (§4) use the agreed palette (Total Sales = blue, Repairs = purple, IPTV = emerald, Outstanding = coral/green) with large values. **Gross sales and outstanding are never mixed** — they are distinct cards with explicit labels.
- **Balanced two-column dashboard** (§5): LEFT is the financial story, RIGHT is who-the-customer-is + recent milestones + relationships. No large card is duplicated — the summary cards are glance tiles; the finance panel is the detailed breakdown.
- **Finance panel redesign** (§6): three aligned headline figures, a **billed / outstanding** breakdown by service with coloured dots (**POS vs IPTV clearly separated; Repairs = n/a** because R1 has no billing), and a two-bar contribution chart with a plain-language percentage. **All figures come from `CustomerFinancialService::overview()`** — nothing is computed in the frontend and store sales are never fabricated.
- **Action bar** (§8): a single compact bar; permission-checked; reuses the existing right-side drawers (Edit, Relationships, Group). **Edit is not duplicated** across sections.
- **Family & groups** (§9) are surfaced inside Customer details with Add family member / Group customer actions and a helpful empty state; existing CRM relationship + group APIs are reused; records are never auto-merged.
- **Recent activity** (§7) shows only the latest ~6 with event icon, description, date/time and a link; the full filterable history stays on the Activity tab.

## 3. Styling & responsive
Palette navy `#123B55` / teal `#008F83` / blue `#0284C7` / purple `#7C3AED` / emerald `#059669` / coral `#E24B50` on `#F1F5F9`. Consistent card padding, subtle shadows, tabular-aligned money, clear section headings; no random gradients, no oversized header, fewer boxes.
- **Desktop 1440/1920:** compact header, four cards, balanced two columns.
- **Tablet 768:** columns reflow; cards wrap.
- **Mobile 390:** single column; finance figures stack (<480px); scrollable tabs; **no horizontal overflow**.

## 4. Testing

### Automated
- **Frontend** `src/pages/customers` + `src/pages/iptv` → **62 passed** (`CustomerProfilePage.test.tsx` updated for the new "Customer details" / "Financial overview" headings and the action bar).
- `tsc -b`, `eslint`, `npm run build` all clean (pre-existing bundle-size advisory only).
- **Backend** unchanged — no logic touched; the C4 finance suite (`--filter=Customer`, 109) remains green.

### Live Playwright (real dev UI)
- Compact header, four summary cards, two-column dashboard, redesigned finance panel + chart, action bar, recent-activity grid all render.
- **No horizontal overflow** at **1920 / 1440 / 768 / 390** and zoom-emulated **125 % (1152) / 150 % (960) / 200 % (720)**; **0 console errors**.
- Screenshots: `screenshots/customer-crm-c5/c5-{before,after}-{desktop,tablet,mobile}.png`.

### Functional (verified in UI)
Six tabs; Edit customer (header); New sale/New repair/New IPTV (action bar + header deep-links); Add note; Add family member + Group customer drawers; finance values + contribution chart from the ledger; last sale/visit/repair/IPTV milestones; recent activity links; permission/tenant boundaries (finance 403 without payments.view; actions gated).

## 5. Remaining gaps (unchanged from C4; out of scope for a layout pass)
- **Appointments backend** (table + API + reminders) — tab is a placeholder; an `appointment` activity kind is already wired.
- **Repair billing** — none in R1, so repair finance reads `n/a`.
- **Store-credit balance** — no modern equivalent of the legacy `customer_details.balance`; "Outstanding/Balance" means amount owed.
- **Multi-currency finance detail** and a **server-side audited activity endpoint** remain future increments.

## 6. Commits (local only — no push)
- **Frontend:** `4a4c228` — compact header, four summary cards, two-column dashboard, redesigned finance panel, action bar, activity-below.
- **Backend (docs only):** this commit — this report + before/after screenshots.
