/* Shipright — public feed.
   Identity: "Instrument" (docs/brand/brand-kit.md). Chalk and graphite, an
   engineering-drawing grid, orange industrial arms, lime only as a fill.
   An advanced-mainframe console: lamps, monospace readouts, job records.

   Fonts are IBM Plex (SIL Open Font License), served from this site's own
   fonts/ folder. Nothing is fetched from a font service. Each brand face has
   a size-matched stand-in built from a common system font, so text does not
   jump when the real font arrives. */
