Logo files

Every mark comes in the same set of files, in assets/logos/<mark>/:

Folder	What’s in it
`svg/`	Vector files. Use these wherever SVG is accepted.
`png/`	Pixel files from 16 to 1024 pixels. Sizes of 48 and below use the small version.
`web/`	Ready-made website icons: `favicon.svg`, `favicon.ico`, `apple-touch-icon.png` and web manifest icons.

File names follow <mark>[-small][-variant][-size]:

Variant	Background	Best for
(none)	Transparent, for dark backgrounds	Docs site headers in dark mode, slides, video
`-light`	Transparent, for light backgrounds	Docs site headers in light mode, print on white
`-tile`	Ink rounded square	App icons, favicons, cards
`-square`	Ink square, edge to edge	Avatars on platforms that crop or round corners themselves
`-circle`	Ink circle	Stickers, round badges
`-layered`	Ink rounded square, one named layer per ring	Editing in Inkscape, Figma or Illustrator

The single-colour versions are in assets/logos/mono/, in ink and in paper, for print, embossing and watermarks. Also for the one printer in every office that only does black.
