/* Glitch Text Lab v2 — polished dark neon (preview copy, 2026-11-01).
   Same HTML/JS as v1: only this stylesheet changes. No external requests,
   so the site stays fast and fully offline-capable. Neon is restrained:
   glow on the brand, tool panel and primary button only — never on body
   text, so long reading stays comfortable. */
