/* app.css - Where The Work Is
 *
 * One surface, one ink scale, three data hues. The data hues are the project's
 * matplotlib palette re-stepped for a dark surface (blue #3987e5, orange
 * #d95926, aqua #199e70, plus red #e66767 for the negative half of a diverging
 * pair). Every one of them clears 3:1 against the surface. Nothing else on the
 * page is allowed to use a data hue as a fill.
 *
 * Depth comes from three cheap layers and no filters: a fixed ambient wash, a
 * fixed grain tile, and a hairline of light along the top edge of every raised
 * surface. All three are painted once and composited; none of them repaint on
 * scroll, which matters because this page animates eighteen circles at once.

     side panel, stacked, tall ->  legible, but it pushed the prose off screen
                                   because the panel did not really scroll
     strip under the player    ->  `height: 14vh` + `width: 100%` gave a 4:1
                                   letterbox slit: you could not see the person
     strip, sized by height    ->  legible, but beside the story rather than
                                   with it, and it cost the chart 190px
   This is the fifth and it is what was asked for: keep them beside the text,
   full width of the column, and let the column scroll. `.p-side` already has
   `overflow-y: auto` and `justify-content: safe center`, so as soon as the
   content is taller than the panel it aligns to the top and every part of it
