# frontend-designer — MEMORY (L1 HOT)

> 8th sub-agent (S47, 2026-06-02). Role: FE **design/UX/aesthetic** cho 2 app SOLUTION_ERP. Floor FD1–FD10 (AI_INFRA canonical, KHÔNG hạ). Forked `frontend-designer.agent.template.md`.

## Role + boundary
- **MINE:** FE design/UX/redesign — `fe-admin/src/**` + `fe-user/src/**` styling/component/page/design-system/a11y/responsive/micro-interaction. Design-by-code (React/Tailwind/shadcn), KHÔNG Figma.
- **NOT MINE:** BE/DB/business-logic (implementer-backend) · cookie-cutter mechanical mirror theo spec (implementer-frontend — **KHÔNG double-touch cùng file UI**) · test (test-specialist).
- **store_memory GỠ** (broadcast 2026-06-02) → ghi finding/token/component vào FILE NÀY; em main + re-index đưa vào RAG.

## SE design-system (FD1 — DÙNG, KHÔNG reinvent) — VERIFIED S47
- Brand primary **`#1F7DC1`** · font **Be Vietnam Pro** (Vietnamese diacritics) · Tailwind tokens · ERP shell (TopBar + Bell + UserMenu).
- ⚠️ **Token source = Tailwind v4 CSS-first** (NO `tailwind.config.js` file — template path stale). Tokens live in `fe-user/src/index.css` `@theme{}` block (mirror `fe-admin/src/index.css`). Read TRƯỚC khi build.
  - Brand scale `--color-brand-50..900`; **`--color-brand-600 = #1f7dc1`** (exact logo). Accent red `--color-accent-500/600` (from ® mark). Be Vietnam Pro + JetBrains Mono via Google Fonts `@import` in index.css. body 14px / lh 1.55 / letter-spacing -0.003em.
- UI primitives are **hand-rolled cva** (NOT vanilla shadcn copy): `fe-user/src/components/ui/{Button,Input,Label}.tsx`. Button variants primary/secondary/outline/ghost/danger × sm/md/lg; focus-visible ring brand-500 + disabled:opacity-50 already wired. Input has focus-visible border-brand-500 + ring. REUSE these, don't reinvent.
- Stack: React 19 + Vite 8 + TS 6 + TanStack Query + lucide-react + sonner. Node v22 local (engines `>=20`).
- UI 100% tiếng Việt · Named export (trừ App) · TS6 `const X = {...} as const` thay enum · PageHeader chỉ {title, description, actions} · Duplicate 2 app CÓ CHỦ ĐÍCH (§3.9).

## FD2 visual-verification rig (SE-specific) — ✅ VERIFIED RAN end-to-end S47
- Dev: `cd fe-admin && npm run dev` → :8082 (proxy /api→:5443) · `cd fe-user && npm run dev` → :8080.
- Auth: ERP behind login — token localStorage `solution-erp-admin-token` / `solution-erp-user-token`. Authed page screenshot cần API+SQL chạy + login fixture (seed JWT). Public `/login` chụp trực tiếp.
- **PROVEN rig** (`webapp-testing` skill = Python Playwright, NOT npm @playwright/test):
  - Bash tool is **POSIX bash** despite env "PowerShell" note → use `cd "abs/path"` (NO `cd /d`). Forward-slash Windows paths work.
  - Chromium for Testing already installed (`C:\Users\pqhuy\AppData\Local\ms-playwright\chromium-1223`). Python 3.11 + `playwright` binding present & drives headless OK. NO install needed.
  - Run pattern: `python <skill>/scripts/with_server.py --server "npm run dev" --port 8080 --timeout 90 -- python my_shot.py` (helper starts/stops dev). Write my_shot.py in fe-user dir, **delete after** (throwaway, not app code).
  - Screenshot: `browser.new_page(viewport={w,h}, device_scale_factor=2)` → `page.screenshot(full_page=True)` → **Read PNG** to NHÌN.
- 🪲 **2 Vite-dev gotchas (cost me 2 failed runs):** (1) `wait_until="networkidle"` NEVER fires — Vite HMR websocket stays open → use `domcontentloaded` + `wait_for_selector("form")`. (2) FIRST goto after cold server triggers Vite dep-optimize compile (>15s) → add a **warm-up goto with 60s timeout** before the viewport loop, else first viewport times out.
  - 🪲 (3) **Authed-page (Dashboard…) S55 BLOCKER:** `dotnet run` API binds **HTTPS :5443** + HTTP :5444 (Program.cs overrides `ASPNETCORE_URLS`), nhưng `vite.config.ts` proxy target = `http://localhost:5443` → protocol mismatch → /api login fail → kẹt /login. ĐỂ chụp authed: temp-set proxy `https://localhost:5443` (`secure:false` sẵn) + restart Vite + **REVERT sau**; HOẶC run API HTTP-only. + Dashboard = ProtectedRoute (cần JWT) → Playwright login THẬT (fill `admin@solutions.com.vn`/`Admin@123456` + submit + wait url≠/login). S55 rig này chặn cả designer + em main → **đáng tin nhất = deploy prod rồi login thật xem authed pages** (đừng vật lộn dev-rig cho authed screenshot).
- Fallback khi stack chưa chạy: static component preview / screenshot `/login` — **KHÔNG bỏ soi** (FD2 cấm ship-unseen).

## Component inventory (built/verified — chống reinvent)
- `fe-user/src/pages/LoginPage.tsx` — login (public, no auth). Layout: gradient bg + 2 blur blobs + centered `max-w-md` card (bg-white/90 backdrop-blur) → logo / brand eyebrow / subtitle / Email+Mật khẩu / full-width Đăng nhập. Uses ui/{Button,Input,Label}. Solid baseline; nearly identical in fe-admin (mirror candidate).
- `fe-user/src/pages/hrm/EmployeesListPage.tsx` — **2-panel master-detail HRM (S66 refine, was 3-panel S65)**: shell `lg:grid-cols-[22rem_1fr] xl:grid-cols-[24rem_1fr]`. **CỘT TRÁI** = `<div flex flex-col gap-4>` chứa Org-tree (TRÊN, `lg:max-h-[44%] lg:shrink-0`, cuộn riêng) + List+filter (DƯỚI, `flex-1`, cuộn riêng). **CỘT PHẢI** = Detail 5-tab (flex-1, rộng). <lg → 1-col (tree→list→detail) + mobile tree-toggle `treeOpenMobile` (tree `hidden`→`flex`). Org tree = recursive `TreeNode` consume `GET /api/departments/tree` (DepartmentTreeNode {id,code,name,parentId,directEmployeeCount,totalEmployeeCount,children}); gốc "SOLUTION COMPANY" (`companyOpen`) → `pickDept(null)`=all; `CountBadge` (totalEmployeeCount, active=brand-600 fill) → `deptId` URL param. Detail = avatar header (`.app-gradient-brand` + initials-in-rounded-2xl) + 5-tab nav (Tổng quan/Thân nhân/Trình độ/Kinh nghiệm/Hợp đồng) count pills + brand underline. **Accent system (S66 việc 2+3):** `type Accent='brand'|'teal'|'violet'|'amberx'|'greenx'` + `ACCENT` map (chipBg/chipFg/head/rail/labelText). `Card` nhận `accent` prop → `.icon-chip` tinted (`--chip-bg`/`--chip-fg` inline) + heading `text-{x}-700` + left rail pseudo `before:content-[''] before:w-1 before:bg-{x}-500` (clip qua overflow-hidden). `Field` label = `text-{x}-700` uppercase semibold (was slate-400), value = `font-medium text-slate-900` (was slate-800). OverviewTab: 1 accent/card (Thông tin chung=brand, Sức khoẻ/Lương=greenx, Liên hệ/Ngân hàng=teal, Giấy tờ/Đoàn thể=violet, Công việc=amberx). Tab-body sections: family=violet, đào tạo=teal, kỹ năng=greenx, công tác=amberx, hợp đồng=brand. ⚠️ **accent palettes chỉ có stop 50/100/500/600/700 — KHÔNG -800** → head dùng -700 (else Tailwind v4 silent no-class). Reusable: `Avatar`(hash 5 gradients + dim), `CountBadge`, `Card`(+accent), `Field`(+accent/mono/icon/full). **ALL 5 satellite CRUD + 15 satellite api endpoint (+ top-level del + 3 reads) + 3 query keys preserved verbatim** (grep+tsc verified, layout/style-only). fe-admin NOT mirrored (separate pass).

## Anti-slop catches + rubric verdicts
- **LoginPage (S47): rubric PASS.** Anti-generic ✓ (brand #1F7DC1 NOT default-blue, no emoji, lucide-ready, purposeful palette). Fix applied: subtitle "Đăng nhập để tiếp tục" `text-slate-500`→`text-slate-600` (borderline ~4.6:1 over translucent card → solid ~7.5:1, FD5 contrast floor). 1-line, no layout shift, on-scale (FD1). Screenshots: `/tmp/fd2-login-shots/login-{before,after}-{mobile-375,desktop-1440}.png`.
  - ⚠️ **fe-admin parity follow-up:** same subtitle likely `text-slate-500` in fe-admin LoginPage — apply same bump next fe-admin touch (did NOT touch fe-admin this run; scope-disciplined).
  - Minor noted (NOT fixed, out of bounded scope): 2 `blur-3xl` blobs barely visible at 1440 = render cost ~0 payoff; eyebrow `tracking-[0.2em]` heavy. Candidates if login redesign requested.

- **S47 (2026-06-02) FD2 RIG VERIFIED ✅** — first real spawn. Ran full FD2 loop end-to-end on fe-user `/login`: read DS (Tailwind v4 CSS-first, corrected stale config-path assumption) → started Vite via `with_server.py` → Playwright screenshot 375+1440 → Read PNGs → FD4 critique → 1-line contrast fix → re-screenshot confirmed → `npm run build` 0 TS error. Closes adap-report `2026-06-02-Agent-frontend-designer-floor` FD2 runtime proof. 2 Vite gotchas captured above. Loop is REAL, not theoretical.
