Previously, tapping the mic button would reset the textarea each time,
clobbering anything the user had already typed or previously dictated.
Fix:
- Capture _prefix = ta.value when recording starts (btn.onclick)
- onresult writes _prefix + (final || interim) so live interim text
appears after the existing content, not replacing it
- onend commits _prefix + _finalText with smart space insertion:
if the prefix doesn't end with a space or newline, a space is added
before the new transcript so words don't run together
- _prefix is reset to '' in _setRecording(false) so each new recording
session starts with a fresh snapshot
Behaviour now: tap mic, speak, tap again (or wait for auto-stop) ->
transcript is appended to whatever was in the textarea. Tap mic again
-> continues appending further. Text stays fully editable before send.
tests/test_sprint20.py: 6 new tests covering prefix capture, onresult
prepend, onend commit, reset, and smart spacing (52 total, 382 overall).
- index.html: add #btnMic (hidden by default, shown if browser supports
SpeechRecognition) and #micStatus listening indicator inside .composer-box
- boot.js: IIFE-scoped mic handler wired to Web Speech API
* recognition.continuous=false (auto-stops after ~2s silence)
* recognition.interimResults=true (live transcript preview in textarea)
* Toggles .recording class + shows #micStatus while active
* Handles 'not-allowed', 'no-speech', 'network' errors via showToast()
* btnSend.onclick stops active recognition before sending
* Entire feature disabled/hidden gracefully when API unavailable
- style.css: .mic-btn, .mic-btn.recording (red pulse animation),
.mic-status, .mic-dot, @keyframes mic-pulse
- tests/test_sprint20.py: 46 tests covering HTML structure, CSS rules,
JS logic, error handling, and regression checks (376 total, all pass)
