/* ==========================================================================
   05/10/2026: wide screens (brief 10). Below 1600px nothing here changes the page.
   1. Content sits in a centred frame (--maxw); the gutter grows to centre it, and the header,
      sections and footer all pad with the same gutter, so they line up.
   2. --s scales type and spacing on big screens, so a 4K screen at 100% zoom is not tiny.
      systems-map.js and record.js read the same --s.
   3. Extra width is used where it helps: the step list goes two-up, panels get room.

   05/10/2026: wide screens, round 2 (brief 11). The review screens showed headings, intros and lone
   panels hard left with the right half empty, a tall empty band above each inner-page heading, and
   a different frame on different pages.
   1. Inner-page opening (from 1100px): no more 86vh-tall block with the words pushed to the bottom.
      The words keep to the left 56% and the systems map sits beside them (systems-map.js measures
      the same 56%). It is beside the words now, not behind them, so it shows a little stronger.
   2. A panel left on its own in the two-up layout ("solo", marked by page.js) runs the full width,
      heading on the left and text on the right.
   3. Everything wide sits in the same frame: the record block and closing call line up with it.
   4. Landing page: the governance rules sit beside the words; the closing headline uses the width.
