/* ============================================================================
   Thamer Al-Tuwaijri — Portfolio
   Faithful recreation of the design handoff. Tokens are the source of truth.
   Design rules (non-negotiable): no emoji, no gradient cards, no rounded
   shadowed cards, no left-border stripes, no em dashes, sharp corners (radius 0),
   structure drawn with 1px hairlines. Arabic leads; English follows, smaller.
