- When checkbox is checked, hide the bottom '#qr' rendering sample.
- When checkbox is checked, apply the font size slider value directly to the textbox.
- Re-enables the 3L version of the font in tools/build_font.py and Makefile.
- Removes /Downloads/qrfont copy targets from Makefile.
- Adds the --delete flag to the Makefile deploy target for remote cleanup.
- Adds an interactive checkbox to index.html ('Apply QR font to textbox') allowing users to type directly in the QR font and observe zero-advance cursor/shaping behavior.
- 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.
* Revert UNITS_PER_EM = ADVANCE in tools/build_font.py to restore the QR code height to exactly 1.0 EM.
* Revert CSS line-height of the .qr block in tools/build_html.py back to 1.0.
* Change size-slider and size-input range limits from 10-400px to 10-300px, defaulting to 100px.
* Increase .qr line-height from 1 to 1.5 in CSS to accommodate the 1.5 EM high QR glyphs and prevent line overlaps.
* Restore the base-font EM-proportional scaling calculation (scale = (UNITS_PER_EM / unitsPerEm) * LATIN_SCALE) in tools/build_font.py to ensure the Latin text height stays perfectly consistent across all QR versions and matches Plain Sans size.
* Add HTML link rel="preload" tags to load all three fonts in parallel when index.html is loaded.
* Add font-display: block to @font-face declarations to mitigate FOUT when switching between fonts.
* Implement query parameter cache-busting hashes (?h=<sha256_hash>) for the font references generated dynamically during HTML build.
* Expand the Font Size slider minimum limit down to 10px (previously 20px).
* Replace the "Mono" option in the dropdown with "Plain Sans (no QR parsing)".
* Add .qr.mode-sans CSS styling to use Liberation Sans.
* Simplify JS size logic to keep the font size slider always enabled and active for all modes.
* Increase LATIN_SCALE to 1.00 to render Latin text at its full native baseline size.
* Change .qr CSS box-sizing to content-box and add 12px 16px padding to prevent descender vertical clipping.
* Change default demo text from "Download this font:" to "This page:".
* Add qr.jim.sh URL to the font copyright, designerURL, and vendorURL metadata.
* Increase LATIN_SCALE from 0.20 to 0.50 so surrounding Latin text is larger and more readable.
* Add a styled Font Size range slider and number input box to the web page control panel to support dynamic visual sizing (20px to 400px, centering at 200px).
* Rename demo.html to index.html in the build and Makefile output.
* Separate HTML page generation into tools/build_html.py, removing the HTML template and write_demo logic from tools/build_font.py.
* Define correct dependency targets in the Makefile so that changes to tools/build_html.py only regenerate index.html and do not trigger a slow font build.
* Add a `make deploy` target that runs `rsync -avz dist/ psy:/www/qr/`.
