/* Young Bull · /research + /research/:ticker shared styles
   Universe wall (108-ticker filterable grid with cluster-tinted cards),
   in-page dossier panel (slides from right on card click), per-ticker
   parametric page (used by ticker.html), and sparkline strokes.

   Token contract: relies on /styles/yb.css for --layer-* hues + --gold +
   --ink-* + --bg* etc. Stays compatible with both data-yb-theme="dark"
   and "light".

   Per HANDOFF.md Phase 2: ship the v4 universe wall + dossier panel +
   ticker.html parametric template. Cards tint by canonical_layer hue,
   sparklines use rAF + CSS transition NOT anime.js width-tween (pitfall
   #11). Hash deep-link /research#MU opens the MU dossier on load.
