/* ============================================================
   eddieespriella.com — shared site theme
     1. Brand tokens (palette + semantic) and dark-mode overrides
     2. Base resets, type defaults, View Transitions
     3. Brand custom cursor
     4. Masthead (.masthead, .ms-*, theme toggle, hamburger,
        mobile-menu, responsive breakpoints)
     5. Sticky audit pill
     6. prefers-reduced-motion safety net

   Every standard page links this file. Page-specific styles
   (work cards, contact form, CV grid, stack list, essay typo,
   404 layout) stay inline on each page. The audit page (.mast
   instead of .masthead, React shell) is intentionally isolated.
