/* 🔴 THE ABSTRACT — THIS SITE'S OWN DRAWING, AND IT IS A DRAWING RATHER THAN A WASH:
   CONCENTRIC RINGS, the circles a tuning dial is built on.
   🔴 IT CARRIED VERTICAL TICKS UNTIL 13 OCTOBER 2026 AND GEORGE REJECTED THEM: *"those line in the
   background conflict with the graphic below the top button. choose background without vertical
   lines"* — and he was looking at the page, not at the code. The hero's own graphic is a band of
   VERTICAL ticks marking the stations the scan found, so a background of vertical ticks in the same
   amber at the same weight read as one muddle: the two drawings were competing rather than one
   framing the other. **A BACKGROUND MUST NOT BE DRAWN IN THE SAME LANGUAGE AS THE THING IN FRONT
   OF IT.** Rings share no line with the chart, so the chart is the only straight-line drawing on the
   page and it reads at once. The needle that used to hang down it went with the ticks, for the same
   reason.
   Its own fixed layer: the only thing that fades a background image is a mask, and a mask on <body>
   would fade the page's colour and its glows with it. z-index below the content, pointer-events off
   so it can never take a click. */
