/*
 * Home and upload pages: hero, pricing tiers, dropzone, and the

 * from style-src (see CONTENT_SECURITY_POLICY in web/app.py).
 *
 * Deliberately NOT extracted from report_download.html: that template
 * is rendered to a file and bundled into the download zip, then
 * opened from disk. A <link> to /static would resolve to nothing
 * there, so its styles must stay inline to keep the report
 * self-contained - and no CSP applies to it, since it is never served

   section on the same flat page background the whole way down, which
   is a big part of why a plain 1:1 port of that page's content here
   read flatter than the page it's supposed to match. main is
   centered with its own side padding, so breaking a child out to the
   full viewport width needs the standard 100vw/50% trick rather than
   a plain width:100%, which would only fill main's already-inset
   content column. Shared by both .section-band (how it works) and
   .pricing-section, so this targets the .alt class directly rather
   than either one specifically.
   Everything the band contains then needs its own max-width back
   (see the rule below) - .steps/.chip-grid/.pricing-grid otherwise
   have none of their own, since they never used to need it inside
   main's already-constrained column. .section-head is deliberately
