/**
 * FV Core Login Page Styles
 *
 * Owner design pilot (2026-10-08): the auth pages follow the product design
 * language (frontend/DESIGN.md in the Symmetric Strength plugin): ink on
 * white, one rose accent, DM Sans, one quiet shadow step, no gradients. Colors
 * come from the theme tokens (--ss-*, themes/symmetric-strength/assets/css/
 * tokens.css) with the same values as fallbacks. Light only: the product has
 * no dark theme, so these pages carry no prefers-color-scheme overrides.
