/* Cipher design system, part 1: tokens, base and the generic components (buttons, forms, dialogs, menus, tabs, toasts...).
   Part 2 (mail.css) holds the mail-specific components and the three layouts. Same family look as Quill, Stash, ClosedDoor and SkyNet:
   deep navy, the logo's electric blue and gold. No external fonts or images: these two files are the whole look.
   Themes: light is the default; dark follows prefers-color-scheme; <html data-theme="light|dark"> (set by js/theme-init.js from the
   Light / Dark / System control) overrides the OS. The two dark blocks below MUST stay identical: tests/contrast.py fails on drift. */
