/* Safety net for headings on dark fields.
   The rule above sets the navy heading colour on every heading, and a direct
   match beats an inherited one — so a heading inside a navy panel rendered
   #24356A on #002354 at 1.31:1, far under the 3:1 minimum (§9).
   These blocks paint a dark field, so their headings are white. Using an
   explicit colour rather than `inherit` matters: `inherit` only works if the
   container declares a colour of its own, and a panel that sets just a
   background would otherwise pull the page body colour (#333333) down into
   the heading — the same failure in a different disguise.
   `:where()` keeps specificity at zero for the heading part, so a component's
   own title class still wins. */
