Trace the flat-color logo to source/logo.svg (palette-locked to the canonical brand colors via tools/trace_logo.py), and render every avatar/favicon/logo master from the SVG at its exact size (tools/build_assets.py via resvg). Logo assets are now crisp at any resolution — removes the 640px upscale ceiling. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

"""Vectorize the raster logo into source/logo.svg (true infinite-scale vector).
|
|
|
|
The logo is flat cartoon line-art (~4 colors), so we:
|
|
1. Snap every pixel to the exact canonical brand palette (no color drift,
|
|
and anti-aliasing fringes collapse into clean regions), then
|
|
2. Trace the flat image to colored SVG paths with vtracer.
|
|
|
|
Requires the `vtracer` binary (cargo install vtracer).
|
|
Run: python3 tools/trace_logo.py
