/* ============================================================
   GLOBACOM — new-blue-design/relaycsp.css
   Phase 9 Plan 02 — RelayCSP solution-detail page.

   FIRST: full @font-face + :root token block + base rules + hero
   block, duplicated verbatim from new-blue-design/style.css (chrome.css
   defines zero tokens of its own — every page must duplicate the full
   token block, per the CR-01 bug class already hit once in this
   project) — the exact same ranges 09-01 duplicated.

   THEN: 09-01's own new shared Phase 9 detail-page vocabulary
   (.hero-eyebrow, .hero-tag-row/.hero-tag-chip, .detail-section-*,
   .detail-prose, .detail-quote, .detail-step-*), duplicated
   byte-for-byte from new-blue-design/utility-billing.css — no class
   renamed, no property value altered.

   THEN: this page's own new, page-scoped extensions for RelayCSP's
   denser nested-list content — not part of the shared Phase 9
   vocabulary, never edited into utility-billing.css.

   Nav/mega-menu/footer CSS is chrome-owned (D-82) and deliberately NOT
   duplicated here — see redesign/_shared/chrome.css.

     and, per real Chromium rendering at 1280/1440/1920px, still put the
     headline directly across the subject's face/eyes at every width —
     the simulation's estimate was wrong. Re-verified against real
     screenshots this time: Y=100% shows the BOTTOM band of the source
     (hands on laptop, coffee cup, table) with the subject's face entirely
     above the visible crop window — no face left to overlap the headline
     at any tested desktop width. On narrow/tall mobile viewports the box
     flips to height-constrained (Y becomes a no-op; X governs the crop),
     so this Y change does not affect mobile — X stays at 20%, unchanged
     from the prior mobile-safe value.
