/**
 * Variant CSS: newsletter--dark-accent-centered-band
 *
 * Bold centered sign-up on a dark brand band: a small count chip above a big,
 * expressive headline, one intro line, then a VERTICAL form — a wide email
 * field stacked above a full-width button. High contrast (light text on the
 * dark band, KI-020-safe), accent via the emphasized word and the button.
 * Distinct from full-bleed-band (field + button inline on one row): here the
 * form stacks vertically like a sign-up card and the community count opens the
 * section. On the dark surface text uses --text-on-dark and the accent is
 * lifted (color-mix toward white) so it never falls back to an invisible
 * --bg-main. The email input is a visual placeholder. Part of the `newsletter`
 * role.
 *
 * Centering note (A8/A9): every centered child of the alignfull constrained
 * section keeps horizontal auto margins so it stays truly centered and never
 * left-pins inside the full-width band.
