/* ── Why I'm building this (15 October 2026) ───────────────────────────────
   Will's reasons beside one result opened four ways. The words are the
   parent's homepage-copy-finesse.json why, invitation and contact: the first
   paragraph stands as the band's proposition, the other three sit under
   tabs so the band reads as a page rather than an essay, and every word stays
   in the document (without script they simply stack).

   Adapted, not new: the plait is the landing weave's grammar (assets/art.js:
   a brick red and a steel blue cable crossing with real over and under
   breaks, a crossing at each station, drawn once from the left and then
   still); the film frame is the shelf's .film-poster with its play chip; the
   heading, lead and running text are .home-about's measures; the frames'
   ground, hairline and corner are the take-part card's (--home-card,
   --home-line, 10px). Everything is scoped under .why-weave. */
