/**
 * Flamingo Marine — Tabbed Feature Display (V4 strip-3, top half).
 *
 * A horizontal filmstrip stage on top of a 5-tab bar (WINGS / MEGALOUNGE /
 * GEMINITABLE / SERVINGSHIELDS / FLEXSTORAGE). The active tab carries a pink
 * underline. The active feature image fills ~80% of the inner width and the
 * NEXT feature image peeks ~18% from the right edge (matching the V4 mockup).
 * Clicking (or arrowing to) a tab translateX-slides the track so that tab's
 * panel becomes the main image and the following panel peeks, over ~440ms.
 *
 * Each caption is overlaid on its own image, bottom-left, with a soft scrim for
 * legibility — so the peeking panel shows its caption too. prefers-reduced-motion
 * users get an instant slide. With JS off, the WINGS panel sits as the main image
 * and the tabs are inert (acceptable no-JS path).
