/* ============================================================
   BUKA · insights.css — the /insights hub and its articles.

   Two registers on purpose. The hub is ink and amber so it reads
   as part of watchbuka.com; the articles run on the Soft White
   editorial theme (legal.css tokens) because 1,500 words of prose
   on near-black is a punishment.

   House rules observed:
   - no CSS `transition` on transform; movement uses `translate`
   - no `opacity: 0` on content in base CSS
   - 44px minimum tap targets
