/* ============================================================
   WORKS GALLERY — /works/, /works/<field>/, /works/<work>/
   ============================================================
   Loaded only on the gallery pages, after styles.css, so it reuses the
   site's tokens (colours, radii, spacing, type) and never touches the rest
   of the site. Order: tokens → head and fields → tiles → archive → shared
   blocks → work page → gallery → lightbox → diagrams → motion → print.

   Contracts kept from styles.css: no text truncation, no fixed heights on
   text, every interactive target at least 44px, both themes through tokens
   only, everything readable with motion reduced and without JavaScript.
