/*
	TCG Explorer -- the website, in the app's Collector design.

	Self-contained on purpose: the fonts are served from here, and nothing loads from anyone else --
	no font CDN, no analytics, no script. A privacy-respecting app with a site that phones home to a
	third party would be contradicting itself on the first page anyone reads.

	Colours and type follow `ui/theme/Theme.kt` and `ui/kit/Collector.kt`: near-black, hairline
	greys with no tint, one violet accent -- the app icon's -- Space Grotesk with JetBrains Mono for every number,
	code and label. The light scheme is the app's light scheme -- a deeper violet that reads on white.
