**New Features** * Runtime font accessors and new symbol fonts for text, launcher, statusbar, and shared icons. * Added font height base setting to device.properties * Text fonts now have 3 sizes: small, default, large **Improvements** * Renamed `UiScale` to `UiDensity` * Statusbar, toolbar and many UI components now compute heights and spacing from fonts/density. * SSD1306 initialization sequence refined for more stable startup. * Multiple image assets replaced by symbol-font rendering. * Many layout improvements related to density, font scaling and icon scaling * Updated folder name capitalization for newer style
