/**
 * Account pages — sign in, create an account, reset a password.
 *
 * Loaded AFTER tokens.css and pages.css. It exists because the standalone-page
 * stylesheet was written for prose and tables: pages.css has no input styling,
 * no .btn, no .sr-only and no button reset (that reset lives in base.css, which
 * only the game shell loads). Everything a form needs is here, and every value
 * is either a token or copied from the equivalent rule in components.css
 * (.settings-control, .initials__input, .gameover__status--ok/--error) rather
 * than invented.
 *
 * SPECIFICITY NOTE, and it is load-bearing: pages.css contains `.page p`
 * (0-1-1) and `.page h2`. A bare `.field__error` (0-1-0) LOSES to it no matter
 * how late this file is loaded, so every rule here that targets a <p> or an
 * <h2> is written `.page .thing`. Dropping the `.page` prefix silently reverts
 * error text to the ordinary secondary colour.
 *
 * No inline styles anywhere in these pages: they ship `style-src 'self'` with
 * no unsafe-inline, which governs style="" attributes too, so the browser drops
 * them with no console error and the element merely renders unstyled.
