Themes (Phosphor, Pink, Amber, Ice, Terminal) restyle the menu, boot
page and toasts live from the menu; all but Terminal use readable

BAT_ADC (GPIO4) sits between two 100k resistors on the switched supply
rail, so it reads the cell on battery and ~4.4 V on USB; above 4.25 V is

from a LiPo OCV table; the menu shows voltage and source. Menu lists now
wrap at both ends.
Hold the knob to open a six-row menu: save/remove the playing camera as
a favourite (12 NVS slots), play or forget favourites, choose the
source (random insecam or favourites), time per camera, listing,
screen and ring brightness, caption, and reboot into Wi-Fi setup.
Settings live in NVS and override the Kconfig first-boot defaults.
Camera URLs are stored with their COUNTER placeholder so favourites get
a fresh cache-buster on every visit.
ESP-IDF 5.5 + LVGL 9 firmware that plays random public cameras from
insecam.org on the T-Embed's 320x170 screen, live MJPEG where available,
a new camera every 20 seconds. Knob steps through cameras, LED ring shows
the countdown. Auto-detects the original vs CC1101 board, reuses Wi-Fi
credentials from NVS and falls back to a captive-portal setup hotspot.
