… fonts/tick via Kconfig The firmware builds the managed lvgl/lvgl component with CONFIG_LV_CONF_SKIP=y, so main/lv_conf.h has no effect — LVGL options (fonts, tick, widgets) must be set via Kconfig/sdkconfig. Documents the trap behind the silently-disabled fonts and the never-advancing tick (ruvnet#889).

Relates to #889 (documents its root cause). Fix: #890.
What
Documents the LVGL config trap that was behind #889 (and the silently-ignored fonts): the firmware builds the managed
lvgl/lvglcomponent withCONFIG_LV_CONF_SKIP=y, somain/lv_conf.his ignored and all LVGL options come from Kconfig.Adds a short "LVGL / display config gotcha" note to the ESP32 firmware README's Custom Configuration section, covering:
LV_FONT_MONTSERRAT_*inlv_conf.hdoes nothing → useCONFIG_LV_FONT_MONTSERRAT_*.LV_TICK_CUSTOM=1inlv_conf.his ignored → needsCONFIG_LV_TICK_CUSTOMor a firmwarelv_tick_inc()(the cause of the never-refreshing display in ADR-045 display never refreshes — LVGL tick never advances (CONFIG_LV_TICK_CUSTOM unset, no lv_tick_inc()) #889 / Fix ADR-045 display never refreshing (LVGL tick) + add ST7789 LCD HAL #890).Docs-only; no code changes.
