   Forked from McGheeLab Website, adapted with a LIGHT theme + SWCES sunset palette.

   HOW THIS FILE IS ORGANIZED
   01) Design Tokens & Resets
   02) Base Elements & Utilities
   03) Header (Fixed Top Banner + Nav Drawer)
   04) Hero (Video background + headline)
   05) Subnav (Sticky "chips" quick links)
   06) Page Layout, Cards, Grids, Media blocks
   07) Components (Board, Sessions, Badges, Forms)
   08) Footer
   09) Projects / Sessions (Thumb sizing)
   10) SVG Loader / Logo Animation
   11) Responsive Breakpoints
   12) Reduced Motion
   13) Header Logo Overrides (keep logo stable)

   TIP: CSS variables (custom properties) live in :root and are reused throughout.
