/* THE TOOLKIT — the record (2026-07-18).
   The projects register, two instruments:

   THE WALK — the folio index becomes the corridor its own standfirst always
   promised: a title panel and five rooms, walked left to right by the
   reader's scroll, each room at its own hour. Without JS, with reduced
   motion, or on small screens it is a vertical folio — nothing pinned,
   nothing hidden.

   THE BRASS EDGE — each project page opens on the project's own duality
   (shell|room · house|garden · works|opening night · kitchen|room), divided
   by the brass edge. It wipes once on arrival, then becomes a handle: drag
   it, or hold the keyboard arrows, and pull one truth through the other.

   Depends on main.css tokens and scene.css bands. External JS only
   (js/walk.js, js/compare.js) — the CSP trusts no inline scripts. */
