   Phase 0 lock — May 1, 2026
   This file is the single source of truth for brand colors,
   typography, and spacing across:
     - Marketing landing page (granthawali.in)
     - Tenant workspaces ({slug}.granthawali.in)
     - Super admin console (console.granthawali.in)
     - Email templates
     - PDF invoices and reports
   
   Tenant-specific brand overrides (logo, primary_color, accent_color)
   come from the `tenants` table and are injected by theme.css.php
   AFTER this file loads, so tenant overrides win.
