[CLAUDE] FE: content polish — typography + PageHeader + Button/Input/Table

Typography base (both apps):
- 14px base, line-height 1.55, letter-spacing -0.003em — Be Vietnam
  Pro render chắc hơn, dấu tiếng Việt rõ hơn
- h1/h2 tracking tighter (-0.018em), h1 weight 700, h2 weight 600
- Tabular numbers trong <table> (tự động align cột số)

PageHeader:
- Title text-[22px] thay vì text-xl — hierarchy mạnh hơn
- Border-bottom + pb-5 thay flat layout — content-area rõ vùng
- Description leading-relaxed + slate-500 — dễ đọc hơn

Button:
- shadow-sm + color-tinted shadow (brand/20, red/20) cho primary/
  danger — có chiều sâu
- active:translate-y-[0.5px] micro-press feedback
- Ring offset 2 (thay 1) + offset-white — focus ring tách rõ

Input/Select/Textarea:
- h-9 thay h-10 — phù hợp dense table layouts
- shadow-[inset_0_1px_0_...] — inset highlight tinh tế
- Focus: border-brand-500 + ring-brand-500/20 — 2 lớp chỉ báo
- Disabled: bg-slate-50 + opacity-70 — rõ disabled state

DataTable:
- rounded-xl + shadow-sm + border-200/80 — card feel nhẹ nhàng hơn
- Header: UPPERCASE text-[11px] tracking-wider — ERP enterprise look
- Row hover: bg-brand-50/40 (thay slate-50) — brand-tinted hover
- Padding tăng từ px-3 py-2 → px-4 py-2.5 — breathing room
