 * DESCRIPTION: DevOpser brand dark marketing identity (#000 ground, #1e1e1e
 *              hero gradient end, #282828 cards, brand pink #ED166C). System
 *              font stacks only (CSP font-src 'self'); monospace utility voice
 *              for labels, hints, and endpoints. Signature elements: the hero
 *              URL form (the funnel's step 1) beside the gap chart — your
 *              page's outline measured against the pages beating it.
