# Font source and provenance

Casino Grotesk, Casino Lucid and Casino Orbit are built from the custom geometry
in this project. They are not downloaded typefaces renamed for this website.

## Casino Grotesk

`tools/build_font.py` specifies glyphs as coordinates, lines, curves, strokes,
filled contours and optical corrections. Its `FontBuilder` code constructs a new
font from those outlines. It does not load a third-party font as a design source.
The available repository history includes this geometry-based generator in its
initial commit, `e80bf4b` (9 September 2026).

## Casino Lucid and Casino Orbit

These are AI-assisted design studies derived from Casino Grotesk's source,
produced during the website redesign. They share its foundation; they are not
three unrelated designs created independently.

- Lucid introduces a two-storey a, open c/e shapes, round dots, an open r shoulder
  and a slashed zero.
- Orbit introduces wider proportions, rounded rectangular bowls and lower
  crossbars.

`tools/build_alternative_fonts.py` makes those changes to the glyph geometry
before compiling new font files. No external font files are imported or traced.
Both prototypes currently have one Regular style and the same Latin coverage
as the original family. They are not included in the released 3.2 ZIP.

## What this establishes

The checked source establishes how the fonts are constructed. They use familiar
geometric and humanist typographic conventions; originality of construction does
not mean that every letterform is unprecedented. Repository history cannot
establish influences predating that history, and no exhaustive comparison with
all existing typefaces has been performed.

## Tools and license

FontTools builds the OpenType tables and converts font formats. Skia PathOps
combines geometric outlines. These are font-building libraries, not imported
font designs. The font files and source are released under the SIL Open Font
License 1.1; see OFL.txt. The Casino Grotesk download includes its source generator.
