   with `cover`, and an image does not flip. Left alone, the two largest
   pieces of text on the front page land at 1.85:1 and 1.72:1 — invisible.

   Rather than drop the art, re-expose it for a dark ground. invert() alone
   is wrong: it takes the green band to magenta and the pink hands to green.
   hue-rotate(180deg) puts the hues back, brightness and saturate return the
   life the inversion costs, and `screen` against var(--bg) makes the now-
   black ground land on exactly #131519 — the same value as the page, so the
   band has no seam. Measured on the actual file: the lightest pixel behind
   the text goes #FFFFFF -> #461E38, taking the title to 7.52:1 and the
   description to 8.11:1. Both were under 2:1.

   The filter goes on a pseudo-element, not on .hero, because filter applies
   to an element's text and children too. isolation + z-index:-1 puts it
   above the hero's own background colour and below its content, which is
   also what gives `screen` var(--bg) to blend against.

   .compact for good reason.

   contact.html is the exception: it is the one browsing page with a compact
   hero and no theme class, so nothing overrides .hero's shorthand and the
   near-white art paints under a --green title at 1.85:1. This turns the art
   off there. It is a no-op everywhere else — the themed rules already
