   HERITAGE TIMELINE (.htl-*) — vanilla port of Aceternity's "Timeline"
   component. Each .htl-row is its own sticky-context: the year label
   (.htl-year-sticky) pins near the top of the viewport while its
   .htl-content column scrolls past beside it (mirrors the reference's
   `sticky ... top-40 self-start`). A vertical gradient line runs behind all
   rows; #htlLineFill grows from 0% to 100% height as the whole .htl-wrap
   scrolls through view (driven by GSAP ScrollTrigger scrub in main.js, in
   place of the reference's Framer Motion useScroll/useTransform).

/* ==========================================================================
   TESTIMONIALS — infinite marquee
   Vanilla equivalent of the testimonials-with-marquee.tsx + testimonial-card.tsx
   references: a centered title/description header, then an infinite
   horizontal marquee — the testimonials array repeated 4x, animated via a
   CSS "testiMarquee" keyframe (translateX(0) -> translateX(-100% - gap))
   driven by --gap/--duration custom properties, pausing on hover (vanilla
   equivalent of the reference's group-hover:[animation-play-state:paused]),
   with left/right edge-fade gradient masks. Cards use the reference's
   bg-gradient-to-b from-muted/50 to-muted/10 treatment translated to AMPL's
   navy/gold palette, with an initials-avatar (.testi-avatar) in place of the
   reference's Unsplash Avatar photos, since AMPL testimonials are role-based
   and not attributed to named individuals.
