- Zeroconf on our httpd (GET/POST /spotify_info, form body URL-decoded)
and _spotify-connect._tcp via our mDNS (VERSION, CPath, Stack TXT).
- Session task: waits for the app's login blob, connects with the
user's client ID/secret and the configured bitrate (96/160/320 ->
OGG_VORBIS_*), SpircHandler, events logged; cspot exceptions caught.
Starts when source.mode is spotify/auto and credentials are set.
- bell::bellGlobalLogger was NULL: every CSPOT_LOG crashed the board
right after addUser (Load access fault in Session.cpp:67 /
LoginBlob.cpp:58). cspot/bell logs now go to esp_log (UART + syslog);
signed CDN URL tokens are cut from the log.
- esp_audio_codec's own Vorbis decoder clashed with bell's Tremor
symbols: CONFIG_AUDIO_DECODER_VORBIS_SUPPORT / SIMPLE_DEC_OGG off.
- status.spotify_state from the session (waiting / connecting /
connected / login failed / error / disabled / no client credentials).
- Verified from a Mac: device appears, "connected as <user>", access
token fetched with the user's client credentials, track info, audio
key, CDN URL (the step broken upstream), PCM decoded. Without
backpressure a track decodes in ~26 s (b3 feeds the ring).

With the default 10, PTP (2), AES67 TX, SAP, syslog and httpd's
listen/control sockets left ~3 for web clients although httpd allows 7.
A browser's keep-alive connections then made new requests fail with a
reset for seconds at a time (the intermittent 'outages').
Reproduced: with 1 idle connection held, new requests were reset.
After: 6 idle connections held, new requests answered in 6-7 ms.

CONFIG_ETH_TRANSMIT_MUTEX was off, so LLDP (esp_timer task) could hit the
EMAC TX descriptors at the same time as lwIP. PTP adds a third sender.
Verified: OTA-installed build passes its self-test, web/status fine.

- Board checked with esptool: ESP32-P4 rev v1.3 (engineering silicon),
32 MB GigaDevice flash. Rev <3 support and 32 MB set in sdkconfig.defaults.
- OTA partition layout: nvs, otadata, phy_init, ota_0/ota_1 (6 MB each,
below 16 MB), coredump; no factory app. Partition table at 0x10000 so
the bootloader can grow.
- App rollback enabled in the bootloader from the start.
- PROJECT_VER from git describe --tags --always --dirty.
- Empty stubs for the nine aes67_* core components; main logs version
and chip revision.
- Built with ESP-IDF v5.5.5; not yet flashed.
