Feature rows (Beat Phase C, icvoss/django-brickwork#543): alternating
media-and-copy rows. Structural sibling of _feature_grid.html (equal cards),
not a layout option on it: the markup and CSS are a stack of unequal rows.

Required context: none.
Optional:
  heading (str): section intro heading.
  items (list of dicts): {heading, body, media?}. media is pre-rendered safe
      HTML (img or svg). List-shaped, so supply from context.
  An empty items list renders the heading alone (or nothing if that too is
  empty), never a fabricated placeholder row.

Alternation is CSS-only (:nth-child(even) grid placement from md up). Document
order stays copy-then-media on every row for reading and tab order.

States: none.
Accessibility: section h2, each row h3; decorative media is the caller's
  responsibility (aria-hidden on illustrative SVG). Covered via
  sections-*.html after the example collapses to this include.
Responsive: stack below --bw-breakpoint-md; two-column zig-zag from md up.
