Show HN: Full complex text shaping and rendering on ESP32 with 320KB usable RAM

I built an OpenType shaper and renderer that is nearly output-compatible with HarfBuzz. The focus was memory efficiency, so for the first time ever complex scripts like Devanagari, Arabic, and even Nastaliq can be fully rendered on memory-constrained systems such as an ESP32 with 320 KB of usable RAM.
