/* ============================================================
   ramansodhi.com — styles.css

   One light theme, committed to on purpose. Green is the brand
   colour, split into two tokens: --accent for fills, rules and
   strokes (the portrait ring, the metric rules, tile hover), and
   --accent-ink for anything set as text, which is darkened enough
   to pass AA contrast.

   Language borrowed from the reference site:
     · a big first-person headline, one phrase in accent
     · the portrait sitting on a block of colour
     · company logos and names inline, no logo wall
     · work as large tinted cards with serif titles

   Type: a geometric sans carries the page, a serif sets the card
   titles, a mono handles labels. All system faces — nothing is
   downloaded, so there is no font flash.

   Written mobile-first: the base rules ARE the phone layout.
