# Heltec V4 TFT touch firmware — custom partition table.
#
# 16 MB layout with TWO EQUAL OTA app slots so the touch firmware can
# self-update (HTTP OTA via the meshcomod proxy). The app region (app0+app1)
# is split evenly at 3.875 MB each — the firmware is ~2.4–2.5 MB, leaving
# ~1.3 MB of growth headroom per slot. The tiles + spiffs offsets are UNCHANGED,
# so an OTA (or the one-time USB re-flash that installs this table) keeps the
# map tile cache and all user data (/new_prefs, /contacts3, /channels2, chat
# history) intact.
#   - app0 3.875 MB (ota_0)   ┐ equal A/B slots; OTA ping-pongs between them
#   - app1 3.875 MB (ota_1)   ┘ (was 1.5 MB — too small to hold the image)
#   - "tiles" 4.75 MB (subtype 0x83 = LittleFS) for the map tab's tile pack
#   - spiffs 3.375 MB for user data

# Subtype 0x83 = ESP-IDF LittleFS subtype. The Arduino LittleFSFS instance
# in UITask.cpp mounts this by partition label "tiles". SPIFFS.begin()
# matches the first partition with subtype `spiffs` (== our "spiffs"
# partition), so the two filesystems don't collide.
