/* HWS warm-felt identity entry — the only public login surface.
 *
 * Source: docs/design/hws-warm-redesign-20261105/concepts/login.html (frozen
 * round-3 concept), extracted to an external stylesheet because production CSP
 * is style-src 'self'. The page is self-contained (no site.css): warm tokens,
 * centered brand lockup, two soft choices, one-line error, one support link.
 *
 * Tokens come from the Xiaoban warm-felt design system: canvas #FBF4EA, surface
 * #FFFDF9, cocoa ink #3B2A22, jade action #9ED3BE (always with cocoa text).
 * No blue/cold-gray tokens; no external fonts or icon libraries; icons are
 * inline SVG. Motion 200-320ms; prefers-reduced-motion is honoured by both the
 * stylesheet and the navigation script (which jumps immediately).
