 // ========== CSS Custom Properties (exposed to the browser) ==========
 // These map SCSS variables to CSS custom properties so Angular components
 // can consume them via var() at runtime.
+//
+// COLOR variables (color_*, gradient_*) are NOT set here anymore.
+// They are injected at runtime by the SSR server as an inline <style> block
+// so the first paint always carries the correct station colors.
+// Client-side ThemeService.apply() keeps them in sync after Angular boots.
+//
+// Non-color variables (fonts, radii, shadows) remain below as build-time defaults.
