# SD Card Font Families for CrossPoint Reader
#
# This file is the single source of truth for which fonts are generated,
# how they're sourced, and how they're described in the download manifest.
#
# Adding a new font family = adding a block here. No code changes needed.
#
# Fields:
# name: Output family name (used in filenames and on-device UI)
# description: Human-readable description (shown in download UI and manifest)
# intervals: Comma-separated Unicode interval presets for fontconvert_sdcard.py
# sizes: Point sizes to generate
# force_autohint: (optional) Force FreeType auto-hinter instead of native hinting
# styles: Map of style name -> font source
# path: relative to lib/EpdFont (for committed fonts)
# url: download URL (for fonts not in the repo)
#
# Variable fonts:
# Some fonts (Bitter, Inter, Alegreya) are distributed as variable fonts.
# freetype-py can't set variable font axis values, so the build script
# uses fonttools.instancer to extract static instances automatically.
#
# To use a variable font, add a 'variable' key to the style spec with
# axis values to pin:
#
# styles:
# regular: {url: "https://...Font[wght].ttf", variable: {wght: 400}}
# bold: {url: "https://...Font[wght].ttf", variable: {wght: 700}}
#
# Extracted static fonts are cached in instanced_fonts/ (gitignored).
# Requires fonttools: pip install -r requirements.txt
