/* ── the mascot ───────────────────────────────────────────────────────
 * ADAM, through the page.
 *
 * **Not in the hero.** The lockup already carries the ADAM mark, so a figure
 * beside it is the same mark twice, and it showed: wherever it was put in that
 * row it read as decoration looking for somewhere to be. It stands in the
 * closing panel instead, which is the one dark ground on this page and what the
 * artwork was drawn against — and the panel's bottom right is genuinely empty,
 * because the fine print is short and the grid is centred.
 *
 * Absolute inside the panel, which is safe in a way the hero was not: the panel
 * is one box with its own padding rather than a grid that reflows around the
 * copy, so `right` and `bottom` mean the same thing at every width. Below the
 * width where the panel stacks into one column it is not scaled down, it is
 * dropped — overlapping the call to action to keep a decoration is the wrong
 * trade. `overflow: hidden` keeps it inside the panel's rounded corner.
 *
 * **Every pose gets the same box, and that is the whole trick.** The poses are
 * cut to their own content, so their aspect ratios differ — 184x223 against
 * 165x250 against 198x244. Sizing them by height alone gave each one a
 * different width, so four figures that should have read as one motif sat at
 * four different distances from four different headings. A fixed box with
 * `object-fit: contain` makes them occupy identical space whatever shape the
 * artwork is, and `object-position: bottom` stands them all on the same floor.
 * Setting both dimensions also reserves the box before the image arrives;
 * height alone collapsed an unloaded pose to zero width, and every heading
 * below the fold shifted sideways as its figure loaded.
