/* ===================================================================
 * Theme: dayshift
 * nightshift in daylight (01.10.2026, the operator: "eine helle,
 * einladendere Variante"). Same fonts, grid, shapes and building
 * blocks; only the palette is turned over: a cool light ground, white
 * raised surfaces with an outline, ONE dark band per page for the
 * sentence that matters, and one copper accent for what the reader can
 * act on. The token NAMES are kept from nightshift on purpose, so both
 * files stay comparable line by line: --night is the ground here,
 * --worklight the one dark band, --on-dark the text on the ground.
 *
 * Binding document: SPEZIFIKATION.md (German). Read it before
 * changing anything here; the colour roles and the contrast table in
 * it are not decoration, they are the acceptance criteria.
 *
 * SHARED VOCABULARY: this theme uses the same mk- classes as
 * workshop-dark and workbench-paper. The themes are interchangeable -
 * a page is written once, the look hangs on this file alone. Anyone
 * adding a building block adds it to the sister themes too, otherwise
 * interchangeability breaks and nobody notices until the switch.
 *
 * DEPTH WITHOUT BLUR: there is exactly one box-shadow in this file,
 * "inset 0 1px 0" with zero blur - a 1px lit edge on raised surfaces.
 * No drop shadows, no glow, no gradients. See section 6 of the spec.
 * ================================================================== */

/* ===== Fonts =======================================================
 * Local WOFF2 only, paths relative to this file. The files are
 * supplied by the client and are NOT part of this theme. Every family
 * falls back to a system grotesque, so the page stays usable without
 * them. One family, Schibsted Grotesk, licensed under SIL OFL 1.1;
 * sources are listed in nightshift/SPEZIFIKATION.md section 2. Until
 * 01.10.2026 headings were set in Bricolage Grotesque; the operator
 * found it too playful, so headings now use the bold of the text face. */
