/*
 * Eulogikon design tokens — the single palette contract for every bundle.
 * Prepended structurally by stylesheet_registry.py (bundle_content).
 * Role-based names only: one signifier, one referent.
 *
 * Theme resolution (auto + manual toggle):
 *   1. Base `:root`          — light values (default).
 *   2. `@media dark` block   — dark values when the OS prefers dark and the
 *                              user has not forced light.
 *   3. `[data-theme="light"]`— light values re-asserted to defeat the media
 *                              query when the user forces light.
 *   4. `[data-theme="dark"]` — dark values when the user forces dark.
 *
 * By construction the light block appears exactly twice and the dark block
 * exactly twice. When editing either palette, update BOTH of its blocks.
 *
 * Fixed chrome (not mode-dependent, stays literal in site_chrome.css): the
 * navbar and footer slate gradient, the wordmark emboss shadows, rgba-black
 * card shadows, white-on-red PDF badge ink.
