- Mp3Player:
* Disable LV_LABEL_LONG_SCROLL_CIRCULAR during playback (flag ENABLE_TITLE_SCROLL_ANIM_WHEN_IDLE) to avoid screen invalidation starving audio_stream
* Single-line controls [-10s][Play/Pause][Stop][+10s] icon-only, volume slider at bottom, no card/toolbar, time label MM:SS / MM:SS updating every sec
* Seek ±10s with proportional byte calc and correct sample count (was byte vs sample bug)
* Safe history persistence: heap buffer (not stack), recursive mkdir, play_history.txt and volume.txt in user data
* History only for >=10min audios, updated on pause/stop/hide, auto-resume latest
* Full-screen history screen with Back button, open via top-right list icon, playing file highlighted CHECKED, tap to resume long or restart short
- VoiceRecorder:
* Fix crash from lv_label_set_long_mode on icon child in list buttons (force DOT only on last child label)
* Force DOT on status and memo list to avoid scroll anim during audio
* Throttle UI updates (1Hz rec, %/sec change play)
Tested on 192.168.68.107, no crash, heap free ~15KB, screenshot verified
- DiscoveryMountain: new UI optimized for episode list (not player anymore)
- Shows episodes for current season, indicates if on SD card (green=On SD, gray=Not DL)
- Per-episode action: download single via SdDownloader or play via Mp3Player
- DL Missing button for missing eps in season (currently single first missing, batch reverted)
- Season selector screen with cached/total counts
- Top-right X close button
- Seasons/episodes cached to cache.json to avoid network fetch every launch
- Fixes: overlay deletion race (deferred timer), ui_timer leak causing crash on close, season selection overwritten by fetch task
- Fixes: unicode ellipsis squares
- SdDownloader: revert to stable single-file mode (batch array caused crashes)
- Remove batch fields and array allocation, keep single url/path download
- Result bundle simple success/path/bytes
- Mp3Player: add resume position support (pos_sec from bundle, total_sec estimate, total_decoded_samples), return position on exit via bundle for DM to save
Tested on 192.168.68.133: opens, shows S10 2/6, Play/DL buttons, close works, no crash on open/close cycles, cache shows 'Loaded from cache, refreshing...'
