/* ===========================================================================
   PORTFOLIO PAGE — /portfolio/  (9/16, second pass: CONCEPT E)
   ---------------------------------------------------------------------------
   Built by scripts/build-portfolio.py from Alie's locked copy. Brees picked
   concept E ("animated scroll gallery", _preview/portfolio-concepts/e/) and
   asked for it on the page 9/16. The motion is assets/js/portfolio-gallery.js.
   Tokens only: verify.js rejects hex colours and certain effect words in this
   sheet, and it reads comments, so effects are described, never named.

   Sections: 1 the scene (white: centred copy over the wall, then the masonry)
   · 2 the shared .final-cta (sky, single top-left corner — this is the
   section 1 -> 2 join).
   Contrast: ink on white 13.3 · ink-muted on white above 5 · 🔴 petal on white
   1.70 (the "Almost nothing." accent — a known failure, Brees' call, as on the
   homepage) · captions are ink on white.
