/*
 * DotaPrime sign-in pages, variant V1 "Popup panel": one Dota PopupPanel card on the main-menu vignette.
 * Served as /account/style.css under style-src 'self'; no fonts, images or URLs of any kind.
 *
 * The server cannot read the app's src/renderer/design/tokens.css, so the values are copied here and keep the token
 * names of the app (palette --c-* and --dota-*, semantic --bg, --panel, --btn-*, ...). When tokens.css changes one of
 * them, change it here too. Palette used:
 *   --c-black --c-white --c-clear --c-bg-glow --c-bg-mid --c-bg-edge --c-popup-from --c-popup-to --c-popup-border
 *   --c-line --c-title-shadow --c-well --c-accent --c-accent-soft --c-btn-from --c-btn-to --c-btn-hover-from
 *   --c-btn-hover-to --c-btn-border --c-btn-green-from --c-btn-green-to --c-btn-green-hover-from
 *   --c-btn-green-hover-to --c-btn-green-border --c-btn-text-shadow --c-entry-from --c-entry-to --c-tick-border-hover
 *   --c-tick-shadow --c-tick-on-from --c-tick-on-to --c-tick-glow --c-check-label-on --dota-light-grey
 *   --dota-lighter-grey --dota-lightest-grey --dota-loser-red --dota-new-section-green --dota-gold
 * Web-only departures from the app, for WCAG AA and phones:
 *   - field and tick-box border at rest is --c-tick-border-hover (#697879) instead of #444 and #5e686966, which are
 *     below 3:1 on the card;
 *   - controls are 44-60 px tall and field text is 16 px (no zoom on iOS);
 *   - the system font stack instead of Radiance and Reaver (Valve fonts are never served on the web).
