/* The contact page (/hello/): the visitor writes on the studio wall, and Ömür reads along from his desk.
   Its HTML is src/cinematic/contact-page.ts, its behaviour src/cinematic/contact-wall.ts.

   Two layouts of the same form:
   on the wall   body[data-wall]: .plane is glued to the wall's recess by a matrix (960 × 676 at 200 px a metre;
                 .narrow on a phone, 370 × 453), first on a still picture of the room laid in the very same frame
                 (.room), then on the live studio drawn over it (body[data-live]). Sizes here are the wall's own
                 pixels: on a small window the wall is small, and --k (set by the script) keeps the small type readable.
   as a page     everything else (no scripts, a window too small to read the wall in): the same form in a column
                 over the room's soft still. It scrolls.
   The actions are the site's brass ring (buttons.css). */
