/* Build Your Stack — picker-specific styles (page-scoped, additive to styles.css tokens) */

/*
 * Safety net: an authored `display:` on any .stack-* class silently defeats the
 * `hidden` attribute (author stylesheets always beat the UA default `[hidden]{display:none}`
 * rule, regardless of source order). Without this, any card/section given its own
 * `display: flex|grid|block` needs a matching `[hidden]` override or it renders anyway
 * even when JS sets `el.hidden = true`. Concrete case: `.stack-pay-card { display: flex }`
 * had no such override, so the Performance card stayed visible with no booking module
 * selected (James, 2026-07-26 screenshot). Keep this rule; it makes every future
 * .stack-* [hidden] correct by default instead of relying on remembering a per-class override.
