/*
 * The mini-block site's own layer, on top of shared-ui.
 *
 * One thing is loud here and everything else is quiet: the wall, a full-bleed
 * grid where every square is one mini-block and every column is one EVM block,
 * drawn by app.js on a canvas as the sequencer stamps them. A cursor sweeps it
 * left to right and wraps, like an oscilloscope, so a square never moves once
 * it has landed and can always be picked.
 *
 * The rest is type: the headline, the height the wall has reached, five
 * figures measured by this page, the selected mini-block and the raw stream.
 * Continuous motion is the wall's alone, and it stops under
 * prefers-reduced-motion (app.js redraws it once a second instead).
