/* ---- CASCADE LAYER ------------------------------------------------------
 *
 * Everything the kit ships sits in ONE layer named `overscan`, so a consumer's
 * own CSS beats it without a specificity fight and without !important. That is
 * close to mandatory for a distributed kit: an app should be able to restyle a
 * panel by writing a plain rule.
 *
 * ⚠️ ONE layer, deliberately, NOT a sub-layer per file. Sub-layers look tidier
 * and would silently reorder the kit against itself: layer order beats
 * specificity, so a high-specificity rule in an early file that currently wins
 * would start losing to a low-specificity rule in a later one. A single layer
 * preserves source order exactly, so nothing inside the kit changes.
 *
 * Unlayered author CSS wins over all of it. That is the point.
