/* ── Syverro Studio project page ──
   Mirrors the Niqual project-page grammar: shell, hero, problem, strict
   4-column principles grid, role band, next-project nav, frame-breaking
   and responsive behaviour. Differences are intentional and page-scoped:
   Cormorant Garamond identity in the hero, a deep navy ("Studio") visual
   instead of the sand scene, real Studio screenshots instead of a product
   shelf, and no public product CTA.
   The site outer shell (.article-page .site-canvas) has overflow:hidden;
   all deliberate block offsets stay inside the canvas — no page scrollbar,
   no horizontal page overflow. */
