+# Self-hosted fonts
+
+These are unmodified binaries from official upstream sources. Only the faces
+used by the site are retained: Lyth Mono regular/bold, EB Garamond regular/bold
+and their italics, plus each family's regular TTF for build-time outline
+extraction with `opentype.js`. Browsers use WOFF2, not the TTFs. No Nerd, Term,
+Square, Round, variable, light, or medium faces are included.
+
+## Lyth Mono
+
+- Repository: <https://github.com/why-trv/LythMono>
+- Selected non-prerelease release: **v0.10.0**, published 2026-02-06.
+- Pinned tag commit: `71d1cf4f325663705ab41ee1908427ea435b2e5d`.
+- Pinned Iosevka source submodule: `a90e82cf6f37cc9b82e47151024c86cfe0693874`.
+- Official release archive:
+  <https://github.com/why-trv/LythMono/releases/download/v0.10.0/LythMono.zip>
+- Archive SHA-256, checked against the GitHub release asset digest:
+  `06b8c05671572e8cba61bf494404d3b973df348c607cd33f3153a374247d6607`.
+- Extracted only `LythMono/WOFF2/LythMono-Regular.woff2`,
+  `LythMono/WOFF2/LythMono-Bold.woff2`, and
+  `LythMono/TTF/LythMono-Regular.ttf` (hinted versions). The archive is not
+  retained.
+- License: `LythMono-LICENSE.md`, copied from `LICENSE.md` at the pinned commit;
+  SIL Open Font License 1.1, including upstream copyright notices.
+- Internal family: **Lyth Mono**. Regular full name: **Lyth Mono**;
+  PostScript name: **Lyth-Mono**. Bold PostScript name: **Lyth-Mono-Bold**.
+  Regular TTF version: `Version 0.10.0; ttfautohint (v1.8.4)`.
+
+Regular TTF metrics (font units): units/em 1000; hhea ascender 925, descender
+-195, line gap 50; OS/2 typo ascender 925, descender -245, line gap 0;
+Windows ascent/descent 925/245; cap height 720; x-height 540. ASCII `0`, `W`,
+`i`, `p`, and the four box glyphs below all advance **604** units (0.604em;
+8.456px at 14px). This is not a 0.6em font. Glyph count: 12174.
+
+| Character | Unicode | Glyph ID | Ink bounds `(xMin, yMin, xMax, yMax)` |
+| --- | --- | --- | --- |
+| │ | U+2502 | 7535 | (264, -245, 340, 925) |
+| ├ | U+251C | 7561 | (264, -245, 604, 925) |
+| └ | U+2514 | 7553 | (264, 306, 604, 925) |
+| ─ | U+2500 | 7533 | (0, 306, 604, 374) |
+
+These are real, nonempty outlines verified with `opentype.js`, not fallback
+characters. The horizontal stroke's center is y=340, and vertical strokes
+reach the font's 925/-245 line extents. Explicit line-height and vertical
+alignment matter when joining animated strokes to text.
+
+## EB Garamond
+
+- Official source: <https://github.com/octaviopardo/EBGaramond12>
+- Pinned commit: `106a4a6d377987459ae5e68673a4570f13b957fb`.
+- This is the upstream revision recorded by Google Fonts in
+  `ofl/ebgaramond/METADATA.pb` at distribution commit
+  `f8c1d3d6cc75e30d77130bdcbfbff27e3b6233fe`.
+- No published GitHub release is available at the source repository. Files
+  were downloaded directly from that pinned source commit, not a third-party
+  font CDN: `https://raw.githubusercontent.com/octaviopardo/EBGaramond12/106a4a6d377987459ae5e68673a4570f13b957fb/`.
+- Source paths: `fonts/webfonts/EBGaramond-{Regular,Bold,Italic,BoldItalic}.woff2`
+  and `fonts/ttf/EBGaramond-Regular.ttf`.
+- License: `EBGaramond-OFL.txt`, copied from `OFL.txt` at the pinned commit;
+  SIL Open Font License 1.1, including upstream copyright notices.
+- Internal family: **EB Garamond**. Regular full name: **EB Garamond Regular**;
+  PostScript name: **EBGaramond-Regular**. Other included PostScript names:
+  **EBGaramond-Bold**, **EBGaramond-Italic**, **EBGaramond-BoldItalic**.
+- The static regular TTF reports `Version 1.002; ttfautohint
+  (v1.8.4.16-eb64)`. Google Fonts' newer variable version is not included;
+  the static faces above are deliberately used as shipped by upstream.
+
+Regular TTF metrics (font units): units/em 1000; hhea and OS/2 typo ascender
+1007, descender -298, line gap 0; Windows ascent/descent 1047/390; cap height
+650; x-height 400. Advances: `0` 480, `W` 916, `i` 245, `p` 519. Glyph count:
+3247. It does not contain the four box-drawing characters above.
+
+## Japanese / CJK fallback
+
+Neither regular TTF maps any codepoints in Hiragana (U+3040–309F), Katakana
+(U+30A0–30FF), CJK Unified Ideographs (U+4E00–9FFF), or Extension A
+(U+3400–4DBF). `あ`, `ア`, `漢`, `日`, and `本` all map to glyph 0 in both.
+Do not use their `.notdef` outlines for Japanese glyph extraction.
+
+The proportional CSS stack uses installed `Noto Serif JP`, `Hiragino Mincho
+ProN`, `Yu Mincho` / `YuMincho`, then generic `serif`. The mono stack retains
+system monospace choices and installed `Noto Sans Mono CJK JP`. These are
+fallback names only: no additional CJK font is downloaded or requested from
+an external provider. Japanese metrics depend on the user's installed font.
+
+## Build-time outlines
+
+`src/lib/landing-glyphs.mjs` uses `opentype.js@2.0.0` during Astro rendering.
+It reads `public/fonts/LythMono-Regular.ttf` from the site working directory,
+extracts box glyphs directly through cmap (no programming ligatures or GSUB
+shaping), and normalizes the vertical cell to the 24px tree row. Direct glyph
+lookup also avoids Lyth Mono's contextual GSUB lookups that OpenType.js 2.0.0
+does not support. The 0.604em advance and glyph stroke width are retained.
+
+The resulting SVG paths are emitted into static HTML; neither the parser nor
+the TTF is fetched by the browser. Anime.js controls the shared tree transform
+and reveals the persistent trunk through a mask; there is no switch back to
+HTML box-drawing text on completion. Labels and normal content remain text.
+
+## Integrity
+
+`SHA256SUMS` records every font and upstream license in this directory. Verify
+from this directory with `sha256sum --check SHA256SUMS`. Individual hashes
+pin the exact binaries even if upstream tags or release assets change.
