/* The Sound Builder — board 3 of the ambience room.

   Everything structural is site.css and forge.css: the specimen card, the
   red seal, the chip buttons, the engraved rule. These rules lay out only
   what the other two boards have no equivalent of — a knob row with its
   blurb under it, two figures drawn on canvas, and a recipe you can read.

   One pillar-box red on the page (art/street/STYLE.md, treatment A): the
   LISTEN seal. Everything else is ink on paper; a slider a visitor has
   touched says so by taking the ink, not a second colour. */
