master/logo-mark.png	The master: 1024 x 1024 PNG, transparent background. A glossy indigo box with an upward arrow and sparkles.
logo-mark-256.png	The mark alone at 256 px (README, teaser video). Made from the master.

Source. Generated with the image model gpt-image-2.5-sunburst and picked by the owner on 2026-10-11. The master is the model's output, copied unchanged (it keeps the model's C2PA content credentials). Nothing is painted into it afterwards: the background tile, the sizes and the small-size monogram are made in code.

Every other logo file (desktop app icons, .icns / .ico, Windows tiles, favicons, web app icons, the site and desktop header marks, site/og.png) comes from tools/brand-assets.py (Python with Pillow, a build-time tool):

python3 tools/brand-assets.py                  # rewrite every file from the master
python3 tools/brand-assets.py --sheet out.png  # plus a contact sheet of every size

Method: trim to the alpha bounding box, pad about 6 %, square, LANCZOS down, never up. The tile is a rounded square with a navy to indigo gradient from the site's colour tokens. Below 48 px the box and arrow turn to mush, so that tier is a bold "s" set in the system font on the same tile, rendered at the target size. Do not run tauri icon (it shrinks one image to every size). There is no hand-written SVG version of the mark (tests/no-handmade-svg.test.ts).
