/* Petromix Middle East · Price Offer (A4 print template)

   The supplied price-offer.css, with three changes for living inside the app:
   · its `body` rules are gone — they would have restyled the whole app; the
     preview frame (.ov) does that job instead, only while an offer is open;
   · `Inter` is the app's self-hosted face (theme.css), so no Google Fonts;
   · a print block at the end prints the OFFER, not the app behind it;
   · its @page rules (A4, the address footer, page numbers) moved to offer.js
     as OFFER_PAGE_CSS, injected only while an offer is open — @page cannot be
     scoped by a selector, so here they gave Ctrl+P ANYWHERE in the app the
     offer's margins and footer. */
