/* ============================================================
   Amlak — design tokens (DESIGN.md §4 — supersedes PLAN-E §E0-E5)
   "Nothing outside this file contains a hex value." Every colour,
   size and spacing value in the app comes from here.

   DESIGN.md's own palette/type/space variable names (--navy,
   --paper, --rule, --serif, --t-title, --s4, etc.) are the
   canonical set below. The older PLAN-E names (--brand-navy,
   --bg-page, --font-display, --text-xl, --space-4, etc.) are kept
   as aliases onto the SAME values so earlier work (report-owner-
   statement.php, the global .num/.kpi rules) keeps resolving
   correctly without a second palette existing — see DESIGN-NOTES.md.

   One deviation confirmed with Omar in the previous pass, still
   true here since the underlying files didn't change:
   Source Serif 4 and Noto Naskh Arabic are variable fonts — Google
   serves ONE file covering the whole weight range, so each has a
   single @font-face with `font-weight: 400 700` rather than three
   separate static-weight files.

     used to explain why --bg-page stayed white while the warm-page rollout

     reads --page directly (not through this alias), and .shell-container
     carries its own explicit --surface + --rule border, so every page
     already has the warm-canvas/white-content split regardless of what
     --bg-page itself resolves to. --bg-page is kept at --surface (white)
     only because report-owner-statement.php's `.statement-doc` wrapper
     still reads it directly, and that wrapper is a content block — it's
