/* ==========================================================================
   Nooshin Boroomand — Portfolio
   Visual language carried over from the 2021 site: Muli/Mulish throughout,
   heavy 800 headings, navy headings on gray body text, the pink accent,
   soft-shadow cards at 5px radius, and the fixed left sidebar.

   Two deliberate departures from the original, both for WCAG 2.1 AA:
   - the pink is #e70d3f in light mode (the original #f21e4e is 4.14:1 on
     white, which fails AA for normal text) and #f32b5a in dark mode
   - focus outlines are visible; the original set outline:none globally
