/* ============================================================
   TeamBoard - theme + premium polish layer
   Loaded AFTER app.css so the dark theme (in app.css :root) stays
   exactly as built, while this file adds:
     1. light-theme token overrides under [data-theme="light"]
     2. a few new tokens so hardcoded dark values can flip per theme
     3. the dark/light toggle control styling
     4. tasteful Apple-level micro-interactions + loading states
   The whole theme is expressed in CSS custom properties, so no view
   code knows which theme is active. The dawl brand identity (Brand
   Orange #EB522A, Nunito ExtraBold + DM Mono, lowercase "dawl" +
   orange-dot wordmark) is shared by both themes; the espresso brand
   rail stays dark in BOTH so the brand anchor never weakens.
