Every value on this page is read at build time: the swatches, chips and families from Two ramps, both declared unconditionally so either is reachable in either colour mode. Ink is the dark-first ground Cairn is drawn for; paper is the light ramp. Every surface that renders a category accent as text pins the ink ramp rather than following the colour mode, because an accent is a dark-ground text colour. One accent per span category ADR-0009 recommends — 24 of them — plus the neutral default. They are constant across colour modes because they encode a category, not a surface, and they are fixed by ADR-0009: this site consumes them and never redefines them. A category outside the recommended set is not a new colour. Any category name ADR-0009 does not define — anything the record has not decided on — renders in the neutral default, A type badge is machine content: a JetBrains Mono pill on the pinned machine surface, outlined and lit with a dot. It carries its own label, so it is still readable with colour removed. These 8 codes are the ones the design record declares — each is linked to the records that declare it. A badge code is not a category. The record fixes the codes; it does not assign a share type an ADR-0009 span category, so nothing on this site tints a badge from the category palette. They render in the neutral default, If a human wrote it, it is IBM Plex Sans. If a machine emitted it — an id, a path, a span name, a TTL, an HTTP method, a command, code — it is JetBrains Mono. Never mono for a sentence. Both families are declared once, with system fallbacks, so a page stays legible when a font resource fails to load. Everything above was decided in public. --cairn-font-sans: 'IBM Plex Sans', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif cairn.stump.wtf/aB3xQ7 · TRC · 11 spans · 34.2s · ttl 7d --cairn-font-mono: 'JetBrains Mono', ui-monospace, SFMono-Regular, Menlo, monospacewebsite/src/css/custom.css, the badge set from the design record itself.
