- device.properties bump default to 20 - lvgl_fonts add runtime override API (g_runtime_font_size + externs for all Montserrat sizes) - DisplaySettings add fontSize field persisted in properties - Display app adds Font size dropdown 14-28 applying immediately - Lvgl.cpp applies saved runtime font on boot - device.py new bucket <=20 includes all fonts for runtime switching (~150KB) Co-authored-by: internal-model
