// Package brand holds the small monochrome technology marks the site inlines
// beside a technology name.
//
// A mark is path data for a 24x24 viewBox, drawn with fill="currentColor" so it
// inherits the chip's colour and adds no request, no font and no layout shift.
// Marks are opt-in: a technology with no published mark renders as text alone,
// which is the honest default and keeps the chips from looking broken.
//
// The path data is vendored (see icons_gen.go and tools/gen_brand_icons.sh),
// not fetched at build or request time. The marks are trademarks of their
// owners and are used only to identify the technology named beside them.

// slugs maps a technology label, lowercased, to its Simple Icons slug. Labels
