/* ==========================================================================
   AkhilJ.ca — base.css  (Version 2 identity)
   Tokens, reset, typography and layout utilities.

   Global identity = the gallery around the work:
   warm paper, soft white, charcoal ink, warm grey, hairlines,
   and ONE restrained accent (muted wine) used sparingly.
   Projects carry their own colour; the global brand stays quiet.
   Never reintroduce electric blue / coral / loud gradients here,
   and never borrow OmniPhi's cream / gold / serif identity.
