   Two-line caption box over a hero video background. The parent <p

   sized it to whichever line it directly contained text for — and the
   inner block-level <span> for the second line would then overflow or
   underflow that box. Both lines need a single coherent dark backdrop
   that fits the widest of them and provides comfortable padding so the
   text never clips at the edge.

   Switch the parent to inline-block with `width: fit-content` so it
   shrink-fits to whichever child is widest. The span stays block-level
   so it still forces the line break, but takes the parent's content
   width and inherits the dark background. Single coherent dark box,
   both lines fit, comfortable right-side padding. */

   Visually the link is white on the #2c5145 dark-green header/footer

   pa11y's HTML_CodeSniffer engine, ignores the position:fixed .header
   ancestor and computes the link colour against the body's implicit
   white background, producing a false-positive failure. Pin an
   explicit background-color on the link itself (matching the surrounding
   header/footer so it's visually identical) so the walker has a
   concrete dark background to measure against. */

   Pa11y's contrast walker ignores the fixed-position .header ancestor
   and computes the link's text colour against the body's implicit
   white background, producing a false-positive 1:1 reading for the
   white-on-dark-green link. Pinning an explicit background-color on
   the active anchor (matching the header so it's visually transparent)
   gives the contrast algorithm something concrete to measure against
   while preserving the visual design.

   Add an underline as the AT-noticeable indicator since browsers also
   need to convey "active page" to colour-blind users non-chromatically. */
