   BOOSTIO BUSINESS OS — ADMIN STYLESHEET · /admin/css/admin.css · v0.1 (C0)
   --------------------------------------------------------------------------
   Standalone design system for the INTERNAL admin portal ("Business OS").
   Deploys on its own (e.g. ops.boostio.in) — deliberately does NOT depend on
   the marketing CSS or the customer portal CSS. Tokens mirror
   /portal/css/portal.css and /css/boostio.css; keep the three in sync when
   tokens change. English-only (internal tool) — no Mukta, no i18n hooks.
   Light theme only for v0.1; everything already reads semantic vars
   (--bg/--surface/--text…) so a dark block can be added later like portal.css.

   CONTENTS
   00. Fonts (Jakarta headings + Inter body)
   01. Tokens
   02. Base & a11y
   03. App shell — topbar (logo · search · admin menu), sidebar, mobile drawer
   04. Buttons
   05. Cards & KPI cards
   06. Badges, status dots, chips
   07. Data table system (toolbar · sortable · paginated)
   08. Forms (fields, select, switch, search)
   09. Overlays — modal, confirm, drawer/detail panel
   10. Toasts
   11. Audit log entries
   12. Chart cards (SVG charts rendered by js/admin.js)
   13. Menus (admin dropdown)
   14. Empty states & access-denied
   15. Auth (login) screen
   16. Utilities

   RULES CARRIED OVER (CLAUDE.md §2 — non-negotiable):
   · Gradient (--gradient-brand) on at most ONE primary element per screen.
     Each page's head comment states which element owns it.
   · No fake counters, no urgency timers, no stock photos (initials avatars).
   · Numbers tabular (brand rule — kept even on large KPI values for
     consistency with the customer portal's stat tiles).
   · Brand muted #9AA0B4 (--decor) is decorative only — readable muted text
     uses --text-3 #667090 (AA on white and #FAFAFC).
   · CHART PALETTE (validated for CVD + normal-vision separation on white):
     slot order violet #5D16EA → pink #F6197C → deep orange #B33008
     (--orange-700; the 500-step orange sits too close to pink). Fixed
     order, never cycled; status colors are reserved for status.
