 * `color: inherit` is the fix, and it is not decoration.
 *
 * .ml-science__sourcing already sets `color: var(--ml-white)` for the whole
 * band, and this heading was meant to inherit it. It could not: Astra's
 * Customizer CSS prints `h1,h2,h3,h4,h5,h6 { color: var(--ast-global-color-2) }`
 * - #1e293b - and INHERITANCE HAS NO SPECIFICITY. An inherited value only
 * applies when nothing matches the element at all, so a bare type selector
 * beats it every time. The heading rendered #1e293b on #0a2540: 1.06:1.
 *
 * `inherit` re-enables the inheritance Astra interrupted, at (0,1,1), which
 * beats both `h2` (0,0,1) and Astra's `.entry-content :where(h2)` (0,1,0) -
 * :where() contributes no specificity. Restating white here would work too,
 * but then the band's colour would live in two places; this way the heading
 * follows the band by definition.
