   single-thisismyurl_project.css — single portfolio exhibit template

   Built 2026-05-17 from the designer's spec after a render-pass on the live
   exhibit page found that the CSS hooks in main.css were comment skeleton
   only — every block under the "Portfolio exhibit (single) — rebuild
   2026-05-12" banner had been outlined but never written. The template
   markup at single-thisismyurl_project.php was correct; only the styles
   were missing. This file is a from-scratch implementation, not a refactor.

   Conditionally enqueued via inc/setup.php on is_singular('thisismyurl_project'),
   loaded AFTER main.css so unlayered rules here win on conflict. The
   hover / focus / interaction states and the mobile nth-child border
   rules remain in main.css (they load universally and the payload is
   negligible, so duplicating them here would only invite drift).

   Visual register sits parallel to single-case-study.css but image-first
   rather than prose-first:
     - Meta strip is the first row under the hero (Client, Year, Platform,
       Status) as a horizontal data <dl> with vertical rules between cells
     - Actions row below the meta strip carries Visit / Wayback / Repo
       (one primary, the rest ghost)
     - Hero is two-column on desktop (title + lede left, feature image
       right) and stacks on mobile
     - Body owns the numbered H2 counter (counter-reset on .__body, the
       counter() call in main.css's preserved h2::before rule)
     - Engagement record is a quiet provenance aside between body and
       subjects footer
     - Subjects footer renders the taxonomy as pill chips with a labelled
       landmark heading

   Related projects rail — "More projects like this"
   Template part: template-parts/portfolio-related.php
   Render context: portfolio singles only (this file is conditionally
   enqueued on is_singular('thisismyurl_project')).

   Design intent: editorial horizontal-lockup list rather than a mini
   poster-grid. The archive (/portfolio/) uses dark full-bleed poster cards
   with a curated texture pool; reproducing that here would collapse the
   related rail into a visual echo of the archive and strip featured images
   of meaning — the archive deliberately avoids featured images in favour of
   the editorial card pool. These cards surface real thumbnails instead.

   Treatment: three rows, each a horizontal lockup — thumbnail column at
   3:2 on the left, body column (eyebrow / title / outcome / cta) on the
   right. White background surface reads as content continuation rather than
   promoted grid. Section is separated from the exhibit body by a top rule
   and generous block-start spacing. On mobile (≤600px) the thumbnail column
   collapses above the body so the full card stack reads cleanly at 320px.

   Hover state (translateY + gold border + soft shadow) lives in main.css
   at the .portfolio-related__link selector — do not duplicate here.
