/* Numbers.sg brand tokens: Direction A "The Bulletin", chosen by the owner 23 Oct 2026.
   Rules (see research/2026-10-23 plan, #brand):
   - Every number uses --ns-font-num with tabular figures.
   - Rises and falls are shown with ▲ ▼ and a sign in ink, never red/green.
   - Jade is for the brand dot, link hover and focus only; links are plain ink, underlined. Amber only as a "changed today" background behind ink.
   Fonts are self-hosted (SIL OFL 1.1, see ../fonts/LICENSES.md). Preload atkinson-next-latin and atkinson-mono-latin. */
