/* 16:9 stage.
 *
 * The stage is exactly as wide as min(100vw, 177.78vh) and as tall as
 * min(56.25vw, 100vh): on a 16:9 screen it fills the display edge to edge, on any
 * other screen it letterboxes rather than cropping or scrolling. Everything inside
 * is sized in `cqw`/`cqh` container units, so 1920 gives 16 px body text and 2560
 * grows proportionally instead of leaving a small dashboard on a big wall.
 *
 * No `max-width: 1440px` anywhere: that is what used to leave the bottom row of a
 * 1080p screen empty and force a scrollbar.

/* The board is authored at exactly 1920 x 1080 and scaled to fit the window

 *
 * It cannot be laid out fluidly. Plotly draws its tick labels and titles in fixed
 * CSS pixels and re-lays them out only for the space it is given, so a fluid stage
 * at 1351 px wide halves every card while every label stays 13 px: eighteen ranking
 * rows land in a 90 px plot and pile up on each other. Scaling one authored size
 * keeps the composition identical at 1280, 1920 and 3840 - the type gets smaller,
 * the layout never breaks. */
