/*
 * Version 3 -- shared system-import panel.
 *
 * One stylesheet for every system wired to `imports/systemImportController.js`,
 * because there is one panel: `v3-import-*` carries no vendor name and no
 * vendor-specific rule. `v3-perch-import.css` and
 * `v3-force-measurement-import.css` remain in place for the two systems that
 * kept their own controllers.
 *
 * Match status is a word in a badge, never a colour alone -- the badge tints
 * its border and the text inside it says "Matched", "Needs athlete matching",
 * or "Matches more than one athlete". A reader who sees no colour loses
 * nothing.
 *
 * Every table scrolls inside its own focusable wrapper, so a wide preview is
 * reachable by keyboard and the page body never scrolls sideways.
