[CLAUDE] FE-User: redesign density-first theo UI/UX guide AI_INFRA — giữ brand SOLUTION (S58)

Anh yêu cầu sau /check-email ai_infra (guide canonical 13 mục "Surgical
Precision Minimalism", anh-approved 06-11): chỉnh giao diện eoffice giống
guide, GIỮ nhận dạng thương hiệu SOLUTION.

14 file fe-user, visual-only (mirror design system fe-admin S55 + đối chiếu
guide; fe-admin/BE untouched):
- index.css: heading ladder semibold (bỏ font-bold) + .label-eyebrow uppercase
  + tnum note. 6 ui primitives (Button/Input/Label/Select/Textarea/Dialog):
  text-xs font-semibold, control h28-40, rounded-lg, focus ring brand-500,
  bỏ shadow trang trí — variant/size keys + props/forwardRef STABLE.
- 6 shell: DataTable (thead sticky + density px-3 py-2 + tnum + RowActions/
  RowActionButton ADDITIVE luôn-hiện không opacity-hover) / Layout (active
  leaf brand left-rail, logic nav/permission nguyên) / TopBar / PageHeader /
  PhaseBadge (ring-current/15) / EmptyState. + LoginPage polish nhẹ.
- BRAND GIỮ: #1F7DC1 (brand-*) + Be Vietnam Pro + neutral slate (guide cho
  plug hue riêng — chia sẻ grammar, không chia sẻ vocabulary-màu).

Verify: npm build ×2 PASS 0 TS err (fe-user 443ms + fe-admin 8.9s untouched-
confirm). Diff-review từng file: functionality keys stable, additive-only.
frontend-designer return-truncated gotcha #53 giữa FD2 screenshot → em main
disk-recover + self-gate (precedent S55); visual live-check sau deploy.
