even-pretext: Font Measurement Library

Pixel-accurate text measurement for Even Realities G2 smart glasses. Predicts exact layout dimensions matching the LVGL rendering engine in the glasses firmware.

Note: Results may be off for characters not present in the firmware fonts, since the firmware and this library may handle missing glyphs differently in some cases.
