ActivityTicker — pure presentational. Renders a horizontal strip of items
that scrolls right→left over 38s, with CSS mask fades on both edges and
pause-on-hover. Items are duplicated so translateX(-50%) wraps seamlessly.
Hidden entirely when empty (no "no activity" placeholder).
format.ts — small set of formatters used by the ticker and the upcoming
/pulse greeting:
- relativeTime (2m / 3h / 5d / just now)
- redactName ("Maya Rasmussen" → "Maya R.")
- tenureSince (e.g. "2 years, 4 months")
- pulseDateLabel ("MONDAY · 11 MAY", Europe/Copenhagen)
- timeOfDay (morning/afternoon/evening, Europe/Copenhagen)
- tickerItem (ActivityRow + subject label → display struct, with role-dot
colours mapped to existing pigments: copper for pilot, terracotta for
cab, indigo for fenja)
