Media behind

{% comment %}
HERO / media behind: an inverse band with the media filling the whole
area and the copy sitting on top of it.

WHEN TO USE THIS INSTEAD OF THE CENTRED OR MINIMAL HERO. When the product
has a strong piece of art or a screenshot that should carry the visual
weight, and the page can spare the height a full-bleed band needs. It
reads as a statement, so use it once, at the top of a page, not stacked
elsewhere.

This one is the shipped _hero.html component with media_placement="behind":
the copy and media share one grid area, copy on top, over the inverse
surface with a scrim behind it (see _hero.html's own header for the
CONTRAST section: a flat, not gradient, scrim, so the guarantee holds
regardless of copy length or what media the caller passes).

NO MEDIA IS SUPPLIED HERE. The `media` context var is genuinely optional
(a text-only hero renders correctly with the same inverse band and scrim
treatment): this example demonstrates the layout and the inverse-surface
type contract without depending on an image asset. A caller passing real
media supplies pre-rendered, safe HTML via the `media` context var (an
img or an svg); brickwork does not sanitise it.

Required context: none. Optional context: media (safe string, an image or
illustration to fill the band; see _hero.html's own header for the full
Optional context list this include accepts).

States: see _hero.html's own header for the full states contract (none of
  its own: a static band, the CTA button carries its own states).
Accessibility: see _hero.html; the heading renders as the page's own <h1>,
  in the inverse foreground colour for contrast against the inverse
  surface. Covered by axe.spec.mjs against sections-*.html, which renders
  this exact file (both themes); the dedicated WCAG 1.4.3 composited-
  contrast measurement over real pale/dark media is run against the
  separate hero-placement-*.html fixture
  (a11y/generate_fixtures.py's render_hero_media_placement), not against
  this media-less example, since this file supplies no media to composite
  over.
Responsive: no breakpoint switch. media_placement="behind" carries no
  @media rule of its own: the composited layout applies at every viewport
  width (contrast with media_placement="beside", the sibling variant,
  whose two-column layout is gated at --bw-breakpoint-md).
