/* hounds.fun v2 (2026-09-29) — "Hound radar" HUD. Void-black ground, cyan scan lines, mint = live/ok, gold = brand/CTA, red = risk.
   Signature: the radar in the hero (rings = token age, the sweep scores each launch). Everything else is quiet glass HUD.
   Type sizes are fixed (the root stays 16px). Wide screens get a wider layout and more columns, never bigger text. */
