/*
 * Dental SEO Services — "enamel".
 *
 * A clinical-calm page. Deep teal ink on white and a mint ground; one
 * teal-to-sky "floss" gradient (--dn-floss) spent on the numerals, the icon
 * plates, the open strategy panel, the process arch and the closing band.
 * Two motifs carry the subject: four-point sparkle glints (clean teeth) and
 * the smile curve — under the H1, under every stat, and as the dental arch
 * that tells the process. White text never sits on the bright gradient; the
 * text bands use --dn-floss-deep.
 *
 * Everything is scoped under .dn-page. landing.css still loads (the button
 * set and the shared FAQ accordion), so a few rules unpick a shared default.
 *
 * Motion contract (same as the HVAC and AIO pages): [data-reveal] gets .is-in
 * from dental-seo.js on first intersection and each child staggers off its
 * own --i; the reveal is an ANIMATION with backwards fill, so it never
 * replaces a component's own hover transition. Hero elements carry .dn-rise
 * and animate on load. Hiding is gated on .dn-js, added by the script at
 * parse time — no script, nothing hidden. Everything collapses to "visible,
 * still" under prefers-reduced-motion at the foot of this file.
 *
 * Order: tokens, type, buttons, motion, hero, what + stats, helps (bento),
 * services + turn band, strategies (panels), cases (stack) + grow band,
 * process (arch), why, who, leads, FAQ, responsive, reduced motion.
