   AKA TEAM — styles.css

   Built on the same token set and component vocabulary as
   mohamedalaaportfolio.pages.dev, so the team site is the personal site
   with the same hand on it: warm off-white, near-black ink, one deep teal
   accent, mono labels, 12px radius, a single hairline shadow.

   Tokens are copied verbatim from the original build. Change them here and
   both palettes move together.
