   /case-studies/ hub  —  page-scoped layer (2026-09-23)
   Loaded AFTER main.css / v4.css / ui5.css on case-studies/index.html only.

   1. Compact scene hero: the v5 scene as a slim banner so the portfolio grid
      is reached with little scrolling (Dan, 2026-09-23; the glass facts panel
      was removed and the hero cut again 2026-09-25). Same scene and branches,
      copy split into two columns on desktop, title + buttons only on phones.
   2. Slim section header: eyebrow + one-line title + the "tiles play the real
      site" hint, instead of the tall two-line display head + divider.
   3. Three-up portfolio wall on wide screens (two-up on tablets, one-up on
      phones); a short last row splits its width (6-track grid) instead of
      leaving an empty cell.
   4. Every tile carries the client site's REAL hero footage as a muted loop
      that cross-fades in over the still when the tile scrolls into view or is
      hovered (js/cs-hub.js). Opacity only — a playing <video> is never given a
      transform (see memory: never-transform-a-playing-hero-video).

/* ---------- 1. compact hero ---------- */
/* 2026-09-25 (Dan: "this box sucks … remove it … reduce the size of the hero so
   people can get to the portfolio faster"): the glass facts panel is gone and the
   hero is a slim banner. On desktop the copy splits in two — eyebrow + title on the
   left, lede + buttons on the right — so the whole block is one text-row tall, and
   smaller branches set a smaller top pad. Phones keep title + buttons only. */

   5. PORTFOLIO CARD v2  (2026-09-25 — Dan: "take the UI to the next level …
      when people click on view the site (that part is hard to see)")

   The referral wall is the biggest lead source, so each tile is rebuilt from a
   one-click <a> into a self-contained <article> that shows the client's live
   site in motion AND carries a prominent, always-visible "View live site" CTA
   plus a "Case study" link — no more guessing where to click. Navigation is via
   those two real, named buttons only (no mouse-only whole-card overlay: an
   unnamed <a> trips TrollBuster F4 and strands keyboard/AT users). Everything
   below is page-scoped and loads after main.css / v4.css / ui5.css, so no other
   page is affected.
