   Loaded after main.css. Nothing here overrides the template's look; it only
   styles the components the template didn't ship with (skill bars, education
   timeline, project filters, contact details, tech grid).
   Palette and type are inherited from main.css:
     --main-600      lime accent    hsl(72 99% 50%)
