/* The sign-in page (`templates/login.html`). Standalone: loaded after
   `datum.css` with no `shell.css` in front of it, so nothing here may assume
   a shell primitive exists.

   ONE CARD ON THE CANVAS, Datum pattern 9, geometry from mockups v3/v5:
   a 380px card, a wordmark head, a padded body, a banded footer line.
   The code entry is Datum pattern 15 as vendored (`.dt-code-entry`,
   `.dt-code-box`); this file adds nothing to it.

   COLOUR IS ROLES ONLY (KICKOFF C3): every value below is a `var(--dt-*)`
   or a `color-mix` of two of them, so `[data-theme="dark"]` in datum.css
   carries the whole page with no rule of its own here. */
