/* The editorial scaffold shared by every section — lifted from the hub
   landing, where the page reads as one system because of the grid, not
   because of the palette.

   Two vertical hairlines run the whole document; horizontal rules cross
   between them wherever a section changes. Nothing else is drawn vertically:
   interior column rules fought the picture behind the hero's window. */

/* The verticals are ONE fixed overlay rather than borders on each section.
   Borders would have to be re-derived in the hero, the sticky tour track, the
   closing band and the footer, and any of those getting its width wrong shows
   up as a kinked line. A single element cannot disagree with itself.
   `fixed` also means the lines never scroll — they read as the page's frame,
   not as a very tall box. */
