/* Pixel Art Editor. #pxe-scoped.
 *
 * tool-theme.css loads AFTER this file and wins every tie, and two of its rules shape this
 * widget whether it likes it or not:
 *
 *  - `#tool-root button:not(.btn):not([class*="tab"])` is (1,2,1) and gives every button
 *    `padding: 8px 13px` — a 28px floor. That is the rule CLAUDE.md records breaking
 *    texture-maker's palette by 19px. The palette swatches and the material rows here are
 *    buttons with no room for that, so their overrides are written with TWO ids,
 *    `#tool-root #pxe button.x` at (2,1,1), which beats (1,2,1) outright instead of tying and
 *    losing on load order. The toggle buttons carry `pxe-tab` on purpose: the tab rule is
 *    excluded from the generic one, and its active state is the site's own green.
 *  - `#tool-root canvas { max-width: 100%; height: auto }` scales every canvas down to its
 *    column, which would make zoom do nothing past the column width. The stage scrolls
 *    instead, so the canvas is released from that rule, again with two ids.
