Added: - cac3-128.png (Linux desktop launcher size) - cac3-256.png (Debian package icon size) - cac3-1024.png (macOS Retina @2x Qt tray icon) Re-bundled favicon.ico with 16/32/48/96/128/256 sizes inside. Rewrote art/icons/README.md to: - remove references to non-existent SVG sources - document the real PNG regeneration recipe - be straight about the 16x16 legibility limit - leave room for an artist-provided SVG master if/when one exists

# CAC3 Icon Set
|
||
|
||
## Source
|
||
Generated from a 1254×1254 transparent-background PNG master.
|
||
|
||
The PNG is the canonical source of truth for this set. There is no
|
||
SVG master — the SVG you see, if any, will be one you provide or one
|
||
an artist provides. We do not fabricate vector sources here.
|
||
|
||
## Regenerating the PNG set
|
||
|
||
```bash
|
||
SRC=/path/to/your/cac3-master-1254.png
|
||
cd art/icons
|
||
|
||
for s in 16 32 48 96 128 192 256 512 1024; do
|
||
convert "$SRC" -resize ${s}x${s} -filter Lanczos cac3-${s}.png
|
||
done
|
||
convert "$SRC" -resize 1500x1500 -filter Lanczos cac3-app-store.png
|
||
|
||
convert cac3-16.png cac3-32.png cac3-48.png cac3-96.png \
|
||
cac3-128.png cac3-256.png favicon.ico
|
||
|
||
convert "$SRC" -resize 180x180 apple-touch-icon.png
|
||
convert "$SRC" -resize 152x152 apple-touch-icon-ipad.png
|
||
convert "$SRC" -resize 432x432 android-foreground.png
|
||
|
||
# Android background: solid black so the cream disc pops against it.
|
||
convert -size 432x432 xc:'#0a0a0a' android-background.png
|
||
```
|
||
|
||
Requires ImageMagick 7+. The CAC3 medallion has pale-on-mid contrast
|
||
which can collapse under naive resampling — `-filter Lanczos` keeps
|
||
the cream paper disc legible at small sizes.
|
||
|

||
## Note on small sizes
|
||
|
||
At 16×16 the cream paper disc and the dark bear silhouette both
|
||
lighten into the gold rim when resampled down. This is a property
|
||
of the original design, not a render artifact. If this set is used
|
||
as a system tray icon for the wallet, the design may benefit from a
|
||
simplified 16×16 variant — bear head only, no wordmark — that an
|
||
artist provides in addition to the full medallion. That variant
|
||
does not exist yet; it will be added here when it does.
|
||
|
||
## License
|
||
The medallion design is released under **CC0 1.0 Universal** (public
|
||
domain dedication). Anyone may fork, recolor, or remix it for
|
||
downstream CAC3 implementations without attribution.
