/* ============================================================
   Ali3N Dev — the publication stylesheet.

   The colour tokens are lifted verbatim from ali3nstudios.com so the
   two sites are visibly the same company: the same navy grounds, the
   same #38b6ff accent, the same theme-toggle behaviour.

   What differs is everything to do with reading. The marketing site is
   built around cards and a hero; this one is built around a 68ch text
   column, larger body type, real code styling and tables that survive a
   phone. There is no particle canvas and no hero glow on an article
   page — decoration that competes with prose is decoration in the way.
