/* ================================================================
   Resayil — Brand Design Tokens
   Phase 24 (Rebrand + UI Overhaul), Plan 24-02
   ----------------------------------------------------------------
   Source of truth for brand CSS custom properties.
   Consumed by: hooks.py (web_include_css + app_include_css),
   portal pages under erpnext_cli/www/*, Desk customizations,
   and downstream plans 24-03 .. 24-07.

   Design system: design-system/resayil-platform/MASTER.md
   Brand decisions: .planning/phases/24-rebrand-ui-overhaul/24-CONTEXT.md

   Naming: all global tokens are prefixed --rs-* to avoid collisions
   with Frappe's built-in CSS variables and with page-scoped vars
   already used by /subscribe and /brand-preview (which keep their
   unprefixed local --accent, --bg, etc. scoped to their containers).
