/* The site's look, on the Stitch-served gallery pages (/widget/gallery/…).

   Stitch renders our <nav> (pasted into its admin Photo Management page)
   above every public gallery page it serves on this domain, with this
   stylesheet linked after its own widget.css. Two jobs:

   1. The page's palette. Stitch's pages are built on --st-* tokens — the
      same ones gallery.html hands the embedded widget in Stitch.init({theme})
      — and this file loads after widget.css, so the :root block below wins
      at equal specificity and the whole page takes our colours. The values
      are that theme object; change both together.
   2. The nav's own rules. Only those — the site's full stylesheet set would
      fight widget.css over body/html — so a change to the nav in
      css/components.css needs mirroring here.

   Two deliberate departures from components.css, both because Stitch
   strips scripts from the pasted markup and js/nav.js never runs there:
   - The mobile menu opens on a checkbox (#nav-toggle, first child of the
     <header>) that the hamburger <label> toggles, in place of the button
     nav.js wires. The `~` selectors below are what make that work, which
     is why the checkbox has to precede both navs in the markup.
   - The bar is sticky with the solid `.scrolled` background rather than
     fixed with the translucent one: nothing adds `.scrolled` on scroll,
     and a fixed bar over Stitch's page would cover the top of the photo.

   Kept in sync with: the theme object in gallery.html, the tokens named
   below (css/variables.css) and the NAVIGATION block of css/components.css. */

/* Stitch wraps the fragment in .st-chrome-tenant inside a padded page root,

   a plain negative page-padding margin (what coffey-offroad uses) stops the
   bar at the column's edge on any wider screen. calc(50% - 50vw) is the
   full-bleed breakout: it pulls each side out by exactly the gap between the
   column and the viewport, so the bar spans the screen while .nav-inner
   stays centred, as on the site's own pages. The bottom margin gives the
