Kit

Icon set

The official set: a curated subset of HugeIcons (stroke-rounded, free) — the icons a product UI actually reaches for, rendered through the kit's Icon at 1.5 stroke and currentColor. Pick from here first so one concept maps to one glyph everywhere. Click a tile to copy its @hugeicons/core-free-icons export name.

File types

Colored file-type glyphs from Pierre's built-in icon set (the same one trees.software ships), rendered through the kit's FileIcon by filename. Pierre curates a focused set of languages, frameworks, and brands; anything outside it falls back to a generic file.

Brands

Third-party brand marks render as live favicons by domain through the kit's Favicon — a standard approach that stays correct as logos change. Where a domain favicon is the wrong mark (every Google product serves the same generic “G”), an Iconify override pins the real product logo; a globe glyph is the load-failure fallback. Integration-slug lookups live in www/lib/integration-brand-icons.tsx.
