/* v3.7.257: TTS button cosmetic CSS absorbed into design system.
   Layout-only properties retained — design system doesn't provide
   min-height/min-width tokens at this level. Cascade verification:
   wtpp-tts-styles (line ~1459) is BEFORE wtpp-btn-system (line ~1907),
   so design system wins on all cosmetic conflicts already. The
   dropped rules were either dead code (cosmetics shadowed by design
   system) or behavioral duplicates (hover/focus replaced by design
