FONTLOG for Transformer Typeface
===================================

This file provides detailed information on the Transformer typeface.


ChangeLog
---------

2026-03-23  Version 4.1
- Added missing punctuation: " = + % $ * `
- Fixed lowercase i/j dot visibility (single prominent convergence node)
- Fixed hyphen/equals distinction (single bar vs double parallel bars)
- 80 glyphs per weight

2026-03-23  Version 4.0
- Tier 1 fixes: per-glyph sidebearings, 104 kerning pairs (up from 30)
- Tier 1 fixes: bolder Bold weight (strand 14→26 for UC)
- Tier 2 fixes: I/l/1 disambiguation
- Tier 2 fixes: reduced splay on horizontal bar endpoints (T, L, E, F)
- Tier 2 fixes: smoother lowercase bowls (more curve segments)
- Tier 2 fixes: f/t crossbar alignment at y=500

2026-03-23  Version 3.0
- Added complete lowercase a-z (26 glyphs)
- Fixed macOS Font Book validation (name table, gasp, DSIG)
- Added Bold weight with proper OS/2 flags
- Mixed UC-LC kerning pairs

2026-03-23  Version 2.0  "Multi-Head Flow"
- Complete redesign from v1 "horizontal bars" concept
- New concept: strokes as parallel strand bundles
- Convergence nodes and splay endpoints
- A-Z, 0-9, basic punctuation

2026-03-23  Version 1.0
- Initial release (horizontal bars concept, abandoned)


Design Philosophy
-----------------

Each letter is constructed from bundles of parallel strands that represent
attention heads in a transformer architecture. The strands converge at
junction nodes (where information merges) and splay apart at endpoints
(where streams diverge). Decorative elements are rendered thinner than
structural elements to create visual hierarchy.

The font applies standard typographic principles:
- Optical overshoot on round glyphs
- Shape-aware sidebearings (straight/round/diagonal)
- Extensive kerning pairs
- Clear disambiguation of similar forms (I/l/1)
- Consistent visual weight across the character set
