Backfills the working firmware that had stayed uncommitted across the build sessions, so the branch is self-contained. - audio: audio_player, radio_pipeline, sd_player, calm_tone, aac_player - net: podcast (RSS), udp_log - modes: balloons, plus calm/games/radio tweaks - ui: fonts header, icons; build files (CMakeLists, idf_component.yml, sdkconfig.defaults) - docs/superpowers: Histoires design + plan Note: sdkconfig stays gitignored (Wi-Fi creds + tuned LFN/FS/mbedtls settings); a fresh checkout must reconfigure those.
