/* Wooden Ships admin apps: one stylesheet for Inventory Sync (stock) and Image Order Sync (photos).
 *
 * Both apps serve an identical copy of this file (a test compares the two copies byte for byte). They stay two
 * separate apps: this file and the component names are all they share.
 *
 * The page lives in an iframe inside the Shopify admin, which is light, so there is one light theme. One hue carries
 * meaning and nothing else does: red (--urgent) = a piece can sell twice, sales are not copied, photo copying stopped,
 * or the app itself stopped. Everything else is ink and grey. Links are ink and underlined.
 *
 * Contrast (WCAG 2, computed): ink 16.1:1 on white, 14.3:1 on the canvas; ink-2 8.8:1 / 7.8:1; ink-3 6.1:1 / 5.4:1;
 * urgent 6.6:1 / 5.9:1 (5.7:1 on its wash); disabled text 5.2:1 / 4.6:1; control borders 3.5:1 / 3.1:1.
