iso25d.IconCatalog() — the icons themselves are
maintained as Go string literals in iso25d/brand_icons.go, and
this index (plus the SVG files in docs/assets/icons/) is
regenerated by go run ./tools/gen-docs. Do not edit by hand.
Usage on any part: icon: "iso://glyph/<name>" (ink, for light
tops), iso://glyph/<name>/light (white, for dark tops),
iso://glyph/<name>/<RRGGBB> (any color), or
iso://brand/<name> for letter badges.
Custom icons. Beyond the built-ins, icon accepts an http(s)
URL, a data: URI, or a local image file path (svg/png/jpg/
gif/webp — absolute or relative, ~ and file:// accepted). Local
paths are read and inlined as a data URI at render time, so the
output SVG stays self-contained. In Studio, the Edit-details → Icon
field has a Browse… button that embeds a picked file directly.

Adding an icon
Add the 24×24 path markup toglyphIcons (plus a one-line entry
in glyphDescs — a unit test fails if you forget) or a row to
brandBadges in iso25d/brand_icons.go, then run
go generate ./.... The name is addressable immediately.
