Composer footer rendered two near-identical mic icons whose tooltips both
said "Voice input" — push-to-talk dictation and hands-free voice mode were
visually indistinguishable. Researched how ChatGPT/Claude/Gemini solve the
same problem and adopt the industry convention.
Changes:
- btnVoiceMode now uses Lucide audio-lines (6 vertical bars), the
universal voice-conversation glyph. Also registered in LI_PATHS.
- Distinct localized tooltips: voice_dictate ("Dictate") and
voice_mode_toggle ("Voice mode"), with active-state flips
(voice_dictate_active "Stop dictation", voice_mode_toggle_active
"Exit voice mode"). Legacy voice_toggle key removed (it resolved to
"Voice input" in every locale and caused the duplicate-tooltip bug).
- Voice mode is opt-in via Settings -> Preferences ->
"Hands-free voice mode button" (default off). Dictation mic stays
visible by default, unchanged. localStorage-backed; panels.js onchange
calls window._applyVoiceModePref() so the button appears/disappears
immediately without reload.
- 17 regression tests pin: distinct titles, audio-lines glyph, all 4
new keys in all 9 locales, removal of stale voice_toggle, English
labels match convention, pref gating (no unconditional display=''
left in boot.js), Settings checkbox + i18n, panels.js wiring,
active-state tooltip flips.
Browser-verified on port 8789: default state shows 1 mic; enabling
the pref makes the audio-waveform button appear live; tooltips read
"Dictate" and "Voice mode" distinctly.
