/* button.css — THE BUTTON LAW, a verbatim copy of the block in site/styles.css.
 *
 * WHY THIS FILE EXISTS. Founder 2026-08-04: "the add to cart button is not correct ... you
 * violated the rule of buttons fucking yet again. why does it keep fucking happening."
 *
 * Because /templates/ never loaded styles.css. It links catalogue.css, variants.css and
 * standfirst.css and nothing else, so `.btn` and `.btn-primary` are UNDEFINED on the page
 * that sells the templates. Every button there is bespoke by construction, and the card's buy
 * control was duly minted as its own class with its own geometry, hover and transition -
 * which is also what kept magnetic.js's spring from running on it, since a second
 * `transition` on the element fights the inline transform the spring writes.
 *
 * The obvious fix, moving the block out of styles.css, is WRONG: 275 files under site/demos/
 * and ~20 other pages take `.btn` from styles.css and are stamped with nothing. Moving it
 * silently unstyles every sold template's demo.
 *
 * So the block lives in both places and scripts/site/check-button-law.mjs fails the build if
 * they differ by a byte. Two copies with a gate is honest. Two copies without one is how this
 * happened.
 *
 * DO NOT EDIT THIS FILE BY HAND. Edit site/styles.css and run
 * `node scripts/site/check-button-law.mjs --write`.
