/* NEW INTERVENT LOOK — all pages built by build.py (products front page + product pages).
   Kept from the old site: the navy page colour and the cloud photo. Everything on top is new.
   Idea: the page is a night sky. Clouds drift slowly behind; content sits on dark glass.
   Sections: 1 colours + type  2 page + sky  3 header  4 hero  5 product cards  6 footer
             7 fade-in  8 smaller screens  9 PRODUCT PAGE (path, top, description, gallery, viewer)
             10 THE COMPANY on the main page (framed block: statement | photo + figures, ruled grids)
             11 PARTNER LOGOS (the slow strip under the hero)
             12 "Z DZIAŁAŃ" — THE RECORD (large entries, the year-by-year list, an entry's page)
             13 CONTACT (the last block of the main page)
             14 THE MENU ON PHONES (folded behind a button)
             15 THE LANGUAGE BUTTON in the bar (its own look comes from lang-menu.js) */

   button on phones. ".cn__btn.cn-embed" is written out on purpose — the script adds its own rule
   for the button later, so these must be more specific to win (same as on cutlanca.pl). */
