/* Product listing detail page v2 (#4461, epic #4459).
 *
 * The `product` detail page rendered in the shared pp-* / sx-* v2 chrome the
 * other listing families already use, ported from the design prototype
 * `Sigrix_new/marketplace/Marketplace - Listing Product v2.html`.
 *
 * Persona / prompt / skill each carry their copy of this vocabulary inline in
 * their template. Product does not: the page-local `.product-*` classes and
 * inline <style> blocks it used to carry are retired in favour of this file
 * (the epic's Story 2 brief), so the markup stays readable and the rules are
 * cacheable. Everything here is scoped to `body.product-page` so it cannot
 * leak into the pages that still style themselves inline.
 *
 * Accent: the canonical product accent is `#EC6AB8`
 * (`components/_listing_type_colors.html`). Brief §5.4 resolved the drift —
 * the `#C42B6E` / `#B91C5C` values other product surfaces grew are NOT
 * reintroduced here. Light theme needs a darker ink for text-on-white
 * contrast, so it is *derived* from the canonical hex with color-mix rather
 * than declared as a second brand colour: one source of truth, two readable
 * renderings.
