/* lab2/styles.css — blend-a (~70% play-lab x apple IA), decision #315.
   Promoted 2026-07-30 from lab2/index.html's inline block per the second-copy rule:
   this is the ONE shared sheet the homepage and all interior pages load.
   The previous file at this path was the orphaned full-apple pass (rejected 07-28,
   history at db6a410). url() paths resolve relative to THIS file, so they hold for
   pages in lab2/ and lab/ alike.
   Standing rules: type scale untouched (jfk 2026-07-30); red is chrome at <=3
   placements per page, ink text only (cream on --art-red is 3.44:1 and FAILS,
   decision #316); generated art is chrome, real artifacts fill evidence slots. */
