Font resources and portable exports

The font browser presents all thirty DFN resources, with an editable sample sentence, original bitmap samples and byte-labelled glyph sheets. Each resource has downloadable TTF and WOFF2 equivalents.

tools/build_fonts.py reads the original indexed rasters, widths and baseline, then traces each pixel row into square outlines. It does not replace the glyphs with a similar modern typeface, smooth corners or invent kerning. All 223 source slots per font are retained, including blank slots. ASCII maps to ordinary Unicode; every original byte is also available at U+E000 plus that byte. Extended slots are not blindly assigned a DOS code page: the source contains incomplete and potentially custom character sets.

The files include COLR v0/CPAL colour layers and monochrome fallback outlines. Shell colours use REGN1000.DPL; simulator colours use WORLD0.DPL with Roadrunner cockpit palette banks. Other screens and chassis can use different colours. Fonts that differ only in their colours remain separate resources.

The em is 1,024 units and each original pixel is 64 units, so 16 CSS pixels reproduces original pixel size, regardless of whether the source glyph height is 8, 10 or 18. The original baseline and advance widths are preserved. At non-integral sizes, application rasterization may introduce antialiasing. A minimal TrueType program prevents automatic hinting from reshaping the pixel art, notably the small i dot.

The exporter reloads its finished TrueType data through FreeType and compares every one of the 6,690 glyph rasters, colour layers and advance widths against the DFN bytes. WOFF2 character maps and horizontal metrics are checked after round-tripping. Source/export hashes and mapping details are in fonts.json; verification.json records the checks. --check-only runs without writing files.

Original artwork remains attributed to Dynamix / Sierra. These are conversions of the supplied resources, not newly designed fonts.
