   STICK ARENA RESKIN — TITLE SCREEN
   Clones the Stick Arena: Ballistick (XGen Studios, Flash ~2007) boot
   screen: graffiti logo, chunky 3D menu buttons, blinking begin prompt,
   dark warehouse backdrop with animated stick figures
   (animation lives in js/sa/title-screen.js).
   Loaded after sa-core.css — uses its tokens, never redefines :root.
   Markup is fixed in index.html (#screen-title > .title-stage).
