## Summary **What is the goal of this PR?** * Provide a better default weight of Bitter font for improved rendering **What changes are included?** * Changes the default weight for Bitter font that is defined in the custom font catalog to medium (500) from regular (400) for improved rendering on e-ink, especially when font anti-aliasing is turned on ## Additional Context * Bitter font at regular weight can become washed out when AA is on due to some of the thinner stems and posts of the font. Bumping the weight up to medium makes it sturdier and holds up better when AA is turned on. --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.

# 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).
