/* Rat Race Reader — public styles.
   Colours come from the reader's theme (look.css: --bg --paper --ink --muted --line --accent --glow) and, on a work's
   page, from the work itself (works.css: --w-accent --w-deep --w-light). Fonts are self-hosted (look.css): Fraunces for
   display, Inter for the interface, and the reader's chosen face (--f-read) for the reading.
   No inline styles (strict CSP), no images: every picture is SVG or CSS.
   Motion: view transitions between pages and levels, drifting scenes, page turns, reveals as you scroll. The reader's
   "Movement" setting (data-motion: full · gentle · none) calms or stops all of it, and none of it is needed to read. */
