/* tour.css — the guided tour (Tutorial/tour-driver.js; Composer sprint 2, step 3; proposed), in the site's own look
   (style.css: --hud-* tokens, the #00ff88 accent). Classes: lrc-tour-*. The tour's root sits above everything on the
   page (the old slide tutorial is 10050); its spotlight never takes a click, so the page under it stays live. While
   the theater's scrim is up the root yields (`lrc-tour--yield`): the scrim leads the show. */
