/* ===================================================================
   AL-SAYYIDA — Global design system
   -------------------------------------------------------------------
   Mobile-first. Phone layout is the base; the sidebar shell is layered
   on at >=1025px. Authored with CSS logical properties throughout so
   the Arabic (RTL) and English (LTR) directions share one rule set —
   avoid physical left/right in new components.

   Structure
     1. Design tokens            6. Tables (incl. mobile card mode)
     2. Reset & base             7. Forms
     3. App shell                8. Feedback: badges, modals, toasts
     4. Buttons                  9. Page-specific shared pieces
     5. Cards & stats           10. Accessibility & motion
   =================================================================== */

/* ── 1. Design tokens ───────────────────────────────────────────── */

/* --- Palettes -------------------------------------------------------
   Each theme declares only raw --l-* (light) and --d-* (dark) pairs. The
   light/dark resolution below maps them onto the real tokens exactly once,
   so adding a palette never means duplicating the mode logic.

   Selected via <html data-theme="..."> and <html data-mode="light|dark">;
   with no data-mode the OS preference decides.                           */
