/* ============================================================
   PRICE NINJA — Pagina prodotto (PDP) — design allineato al Figma
   Hero card + sezione SERP (filtri + lista offerte).
   Caricato da prodotto.html e da serp-pn.html.
   ============================================================ */

/* Design tokens.
   This file used to assume style.css had already defined every --pn-* token.
   That holds on the product page and the home page, but NOT on the SERP: base.html
   only emits style.css when `css_site.site.name == "Price Ninja"`, a condition that is
   false in production, so on /serp every `var(--pn-*)` below resolved to nothing.
   The effect was silent and partial - `background: var(--pp-accent)` became
   invalid-at-computed-value-time (transparent) while the sibling `color: #fff` still
   applied, rendering the offer button as white text on a white card.
   Declaring the tokens here makes this stylesheet self-sufficient wherever it is loaded.
   Values mirror style.css; when both load the values are identical, so nothing changes
   on the pages that already worked. Single-sourcing the two copies needs base.html to
   load the tokens unconditionally - a wider change, tracked separately. */
