   CONTINUUM MARK PAGE — css/continuum-mark.css
   Loads after styles.css and cursor.css.

   Audit fixes baked in:
   #1 — loader markup removed from HTML (no CSS needed)
   #2 — body prose lifted to 17px / α .82 via --prose-body
   #3 — S3 cards always-visible (no max-height collapse)
   #4 — S2 layer descriptions inline; S4 detail prefilled
   #5 — S6 H2 uses .a (color-only accent), not italic tail
   #6 — copy fixes live in HTML / JS
   #7 — .s3-reconcile note styled below body copy
   #8 — S5 attribution removed (no .s5-attr rule needed)
   #9 — CTA copy lives in HTML
   ORBIT-OVERLAP FIX — .mark-layers strip has opaque backing
