/* Saley sign-in and message pages (auth.py `page`). R5 T16b: the only file left of the R4 static
   app; the dashboard is the built app under /static/app/.
   R5 T17: the page now looks like the dashboard. The colour tokens below copy the values of
   web/src/index.css (light :root, dark .dark) one to one; change both together. The font is the
   app's Geist when the system has it, else the system sans: the bundled Geist file has a hashed
   name under /static/app/assets/, and this page must not depend on a build (CSP D146, no CDN,
   no inline style). Links are Buttons, never underlined text (R5 brief). */
