/* ══════════════════════════════════════════════════════════════
   KEYSTONE AIC
   One stylesheet, three pages. No build step, no dependencies.

   COLOR RULE: orange is structural punctuation, not decoration.
   Roughly three uses per page, maximum. It marks the keystone in
   the arch, the rule above an eyebrow, and one emphasis per page.
   If a fourth orange thing appears, one of them is wrong.
