- All intermediate QR glyphs (header_bits, byte_XX, count, tail,
parity, data bits, parity bits) use native 0 advance in hmtx.
- Only closing base glyphs (qr_base_NN, qr_base_p55_bit_NN) have
positive ADVANCE width.
- No GDEF table, no GPOS positioning adjustments.
- Removes LigateBreak ligature experiment (didn't prevent splitting).
- Fixes Firefox horizontal misalignment caused by subpixel snapping
of GPOS-adjusted or GDEF Mark-classified glyphs.
- Known limitation: Chrome and Firefox may split QR codes across lines
at Unicode break points (spaces, dots, slashes). CSS white-space:
nowrap on QR-containing elements is recommended.
- Temporarily disables 3L font build for faster iteration.
- Separates HTML generation into tools/build_html.py.
- Updates AGENTS.md and design.md with browser layout documentation.
* Add Version 3-L configurations and update documentation (AGENTS.md, README.md).
* Solve OpenType GSUB offset overflows and compiler bottlenecks:
- Combine SetByte lookups per character instead of position/character, reducing the total lookup count from 5,300 to 510.
- Implement useExtension on helper and scan lookups to bypass the 16-bit offset constraints.
- Use class-to-class substitutions for XOR and NoOp lookups.
* Split CloseQR into CloseQR and CloseQR_CountTail to prevent shaper offset mismatches from Multiple Substitutions.
* Remove legacy reference.html output from the build and Makefile packaging.
* Update demo.html style and font selectors to support loading and displaying the 3L font with character limit labeling.
* Keep glyph names in setupPost() to ensure shape_debug.py outputs readable glyph names.
