/* xprhub.com/talks (version 2, 2026-11-08; layout 2026-11-08: the wall first, the composer and the raffle in <dialog>
   sheets, full width on a phone). The hub's purple look (hub/page/hub.css tokens, Inter), copied here so this
   page stands on its own like burns/. Phones: the composer and the raffle stack, the wall stays one column, nothing
   scrolls sideways at 390 px. Post styles: ONLY the st-* classes below (wall.mjs STYLE_CLASSES), never CSS from data.
   Talks revamp (owner 2026-11-09): a small header, the posts as the page on a calm board (their paid styles are the
   colour here), one More menu per post, and How it works folded away at the bottom. */
