Previously the 4-line "identity" screen showed only viewport name, mDNS
host, IP, and state. Expanded to 15 lines covering the full GET /config
+ GET /state output (name, host, ip, state, configured, scrypted,
orientation, brightness, idle, fw, uptime, frames, errs, free heap,
free PSRAM), label/value pairs left-aligned with auto-scaled font.
Renames "identity" → "info" throughout — symbol, log messages,
README/TESTING references.
Also:
- Move the info-screen render's big locals (~1.6 KiB: lines[16][80] +
scrypt[256] + vp_name[64]) to BSS. The touch task's 3 KiB stack
was overflowing on every long-press, leaving whatever frame was
previously on the panel — gave the appearance of a "blue screen"
after the M5 test pattern.
- Drop the ≥5 s touch factory-reset gesture and remove all stale
references to it in docs and comments. NVS wipe is now a USB-side
`idf.py erase-flash` operation only.
- M5 follow-up TODO in jpeg_decoder.c: solid green renders ~black and
solid blue renders green; not a byte-order issue (BGR setting turns
red into blue). Tracked as a known M5 gap.

Holding the touch panel for 5 s to wipe NVS is dangerous (easy to
trigger by accident — phone resting on the panel, kids, etc.) and
useless as a recovery path (factory reset alone doesn't undo a bricked
config; a USB reflash does). Factory reset should be an explicit API
or USB-side action.
Touch gestures now: tap = toggle wake/sleep, ≥1.5 s hold = identity
overlay.

The Waveshare ESP32-P4-ETH board exposes BOOT on GPIO 35, but at runtime
that pin is owned by the EMAC TXD1 signal. No usable GPIO is wired to a
separate user button, so the BOOT-button task could never fire.
Move both BOOT-button behaviours onto the touch panel:
- ≥1.5s hold → 15s identity overlay (was BOOT short-press)
- ≥5s hold → factory reset (was BOOT long-hold)
Short tap (<500ms) still toggles wake/sleep. Long-press fires while the
finger is still down so the user gets immediate feedback at each
threshold.
Also strip the R/G/B 6 s boot test sequence — the panel now renders
correctly, so it's no longer useful diagnostically.
Boot subsystem flags drop the trailing B column: [EMHDJT].

DSI / panel:
- LDO_VO3 acquired at 2500 mV (VDD_MIPI_DPHY) — without this the PHY
PLL busy-waits forever inside esp_lcd_new_dsi_bus.
- PSRAM bumped to 200 MHz (CONFIG_IDF_EXPERIMENTAL_FEATURES) to keep
the DPI fed without underruns.
- Pi-7"-style 800x480 panel init (REG_POWERON, PORTA/PORTB/PWM/PORTC)
+ 16-bit RGB565 framebuffer with portrait-mode rotation buffer in
PSRAM. Currently shows garbled output — known issue, next commit
switches to the TC358762-bridge-aware init sequence.
State + UX:
- viewport_state simplified to AWAKE/ASLEEP only; "unconfigured" is
a flag, not a state. Tap always toggles; content choice (identity
vs frame) is driven by the configured flag.
- BOOT button arms a 15 s identity overlay via local_screens_overlay;
expired callback returns to prior state.
- Boot-done indicator: two backlight flashes (no usable LED GPIO on
the Waveshare board — GPIO 35 BOOT is shared with EMAC TXD1).
- Best-effort subsystem init in app_main; display init deferred to
its own task so a panel hang can't block networking.
Display test pattern: solid R/G/B for 2 s each on boot to characterize
the garble independent of text rendering.

state_client.{h,c}:
- Worker task drains a depth-1 queue (xQueueOverwrite gives the
replace-on-full semantics from the spec — in-flight POST is never
cancelled; the next queued entry is overwritten by newer state).
- esp_http_client POST to <scrypted>/state with Content-Type application/
json, User-Agent ScryptedViewport/<version>, Connection: close, 1s
timeout. Body: {"viewport":"<name>","state":"wake"|"sleep"}.
- Any non-2xx or transport error increments state_post_failures and is
otherwise ignored. Silently drops if no Scrypted URL is configured.
touch.{h,c}:
- FT5426 capacitive touch on the shared I2C bus at 0x38.
- 30ms polling task; tracks down/up transitions, detects taps as
down-then-up within 500ms with a 150ms debounce.
- On tap, toggles wake/sleep via state_machine_set_local(), which drives
the local transition AND fires state_client_post() at Scrypted.
state_machine adds state_machine_set_local(): runs the same transition
as state_machine_set() then enqueues an outbound POST. Idle-timer
expiry now uses this path so Scrypted sees idle-driven sleeps too
(the spec's "tighten the race with /frame 409" path stays in place as
the fallback).
display.h exposes display_i2c_bus(); touch.c uses it instead of
re-initializing the same I2C port.
app_main starts state_client right after the state machine and starts
touch after display init (touch is skipped if display isn't up since
they share the bus).
CMakeLists.txt: add esp_http_client to REQUIRES.
Build clean against ESP-IDF 5.4 (binary ~860 KB; jumped ~210 KB from
M6 because esp_http_client + cJSON path pulls in tcp_transport, mbedtls,
http_parser).
TESTING.md M7: flask-based test receiver, tap dispatch verification,
failure-path check (kill receiver, confirm counter increments),
queue-coalescing behavior, no-POST-on-Scrypted-initiated, no-POST-
when-unconfigured.
