/* Quvor — round 2: "Night × Section".
   One system, two themes. Dark (default) is Night: near-black surfaces lit from above by the Q's
   depth gradient, machined top edges, fine grain. Light is Section: a cool white drawing sheet
   with a faint grid and white cards. Both share the drawing language: rails bounding the page,
   registration crosshairs where section dividers meet the rails, section markers, dimension lines,
   and a title block for a footer. */

   what the caption says, diagnose before building: the sheet is surveyed (centre lines, guide circle),
   the section cut is taken across empty paper with its A arrows, the subject appears as an outline,
   the diameter and the CUT 5 · GAP 1.5 note are placed, and only then is the solid mark built in along
   the cut by a travelling clip. Nothing is built before it is measured.
   Every element runs on the same --cycle so the parts can never drift out of step: the stops are
   percentages of it. The drawing is complete at 66% (3s) and every part holds its last frame. It never
   loops and never replays on click; site.js only pauses it while the figure is off screen.
   Two names to know: the outline is .survey, not .ghost, because .ghost is the site's ghost button; and
   the build clip is referenced from the markup, because url(#id) in this stylesheet would resolve
   against styles.css, and an unresolvable clip-path stops the element being drawn at all. */
