|---|---|
arboretum-logo-source.png |
Master artwork (opaque dark background). Keep; everything else derives from it. |
arboretum-logo.png |
Full logo, transparent. Best on dark surfaces (the wordmark is light). |
arboretum-logo-on-dark.png |
Full logo on the app background #09090b. Safe on any theme — used in the README. |
arboretum-mark.png |
Square, transparent, tree only (no wordmark). Ideal Gitea repo avatar — reads on both light and dark. |
The transparent versions are extracted by luminance (alpha ∝ brightness), the clean way to lift glow-on-black artwork: the dark background becomes fully transparent, the bright strokes stay opaque, and the glow halos stay semi-transparent so the logo sits correctly on any dark surface.
Gitea
Upload arboretum-mark.png as the repository avatar (Settings → uploads a square image;
the tree-only mark stays legible at small sizes and works on Gitea's light and dark themes).
Use arboretum-logo.png (transparent) on dark pages, or arboretum-logo-on-dark.png
when the surrounding background might be light.
App / favicon assets
The web-facing assets live in packages/web/public/ and are wired into the SPA:
icon.svg— scalable favicon, redrawn to match the brand (vector, glow,>_).icon-192.png/icon-512.png— maskable PWA icons (tree on#09090b, content in the safe zone).apple-touch-icon.png— iOS home-screen icon (180×180).favicon.ico— multi-size favicon (16/32/48), transparent.logo.png— transparent full logo for in-app use.
