Headline: TrueType & OpenType fonts, with hinting actually working — and a rewritten fast, clean TTF engine

The TTF/OTF engine was rewritten to use FreeType directly on PSRAM boards (X4 Pro, and any other board with PSRAM), and it's the fast-and-clean kind of rewrite: hinting on so glyphs snap to the pixel grid, and the render path is monochrome 1-bit now, so you don't need anti-aliasing anymore.

What that means on the page:

  • Sharper text at small sizes. Hinting makes glyphs land crisp on the pixel grid, which is exactly where the old unhinted pipeline looked soft and a little blurry.
  • Faster. The FreeType backend reuses open faces and uses a glyph cache + fast face loading, and next-page prerendering is back. Page turns stopped hunting for a font you were already looking at.
  • Cleaner output, no AA. With the FreeType path on PSRAM boards, glyphs render monochrome, so the renderer no longer has to pay the grayscale anti-aliasing pass. Less work on the SPI bridge, cleaner edges.
  • Hinting genuinely works this time. The stack budget that gates hinting was sitting below the real cost of a hinted render, so it switched hinting off for essentially every font — including OTF/CFF faces that crashed the probe on the way in. The budget is now derived from data (the actual 48 KB render-task stack minus a measured margin), backed by a host benchmark (test/hint_mem_bench) that records real per-font stack depth. The probe itself was resized so it reports an over-budget face instead of panicking on it. Both Amazon Ember and Atkinson Hyperlegible keep hinting on now.

If you use custom fonts, drop your .ttf / .otf in /fonts or /.fonts and flash this release — this is the one where it lands.
