/*
  Freeport — the station market's front door.

  The world is ../docs/visual-direction-roadstead.md: a customs docket, ink on paper, colour
  only on leaves, and shape riding with colour so the status spine survives greyscale. The
  palette, the spacing unit and the [data-state] vocabulary are that document's, unchanged.
  Its §9 records every departure, including the three self-hosted faces.

  The layout is deliberately ordinary: one centred column, and cards where there is something
  to hold. An earlier build tried a "docket spine" — a sticky mono field-name in a 13rem left
  rail beside every section — and it failed twice over. It spent a quarter of a wide screen on
  two words, and with no surfaces under the content the page read as though the stylesheet had
  not loaded. Structure has to be visible to count.

  So: two grounds (canary paper, cream card), one accent that means one thing (customs red for
  settled), and headings that announce themselves. Nothing clever.
