/*
 * STAND BY MARITIME — the PC interface.
 *
 * NOT THE PHONE, ENLARGED. The phone shows one thing at a time because a thumb
 * reaches a corner and a screen holds a single card; every constant in that
 * layout is an argument about reach. A mouse reaches everywhere and this screen
 * is wide, so the shape here is the one the phone cannot have: a persistent
 * list beside a live map beside the detail of whatever is selected, all three
 * readable at once, nothing covering anything else.
 *
 * The palette is the app's own (app/src/format.js) so it is recognisably the
 * same product — black ground, amber for anything live or selected, the USACE
 * blue reserved for locks and never spent on a vessel.
 *
 * Type is system UI for the chrome and tabular figures wherever numbers line
 * up in a column, because a mile, a stage and a delay are read by comparing
 * them down the page.
