/* PokerBotsArena homepage · full-screen story (2026-10-24)
   Loaded after site.css on index.html only. Palette from the PBA logo: black, electric lime,
   white, with red and yellow sparks used sparingly.
   html.story-js (set by home-boot.js before first paint) turns the page into one portrait story
   that fills a phone screen, or sits centred on a dark stage on wider screens. Without scripts the
   scenes stack as cards in normal flow, so every word and link stays reachable.
   Rules from site.css still apply: text >= 12px, visible focus, no motion on request. */
