/*
 * The auth surface. One card, centred, nothing else on the page.
 *
 * The vhost sends style-src 'self', so every rule lives here: no inline style
 * block and no style attribute will render.
 *
 * Every selector below groups two spellings on purpose. This file's own
 * classes use the BEM convention throughout. The downstream screen briefs
 * (Tasks 12 to 22) settled on flat names instead, and not even consistently
 * with each other, so both spellings are listed together and resolve to the
 * same rule. Do not remove either half of a group: pick one and the other
 * screen breaks. Class names are deliberately kept out of this comment block
 * itself, so a text scan of a selector never matches prose instead of a rule.
