raft-ui/dist/components/timeline/timeline.css

React UI components for Raft.

/* Timeline pure CSS styling following pattern/Button.css architecture
   - Local CSS variables (--r-timeline-*) declared on the list; items inherit them
   - Modifier classes rebind local variables
   - Component styles strictly consume local variables
   - Every marker is a status pixel: a 9px square in the item's colour with a
     1.5px sticker-ink edge, strung on a hairline. Titles are 14/20 ink,
     details and times Space Mono 12 in ink-3, the time on the right of the
     row. One scale for every size; `lg` only opens the title to 16/24.
