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.
• 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).

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.

Activity log

• 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.
