/**
 * Variant CSS: features--interactive-tabs-photo-static
 * Layer 2 — Path B features role (2026-06-06).
 *
 * Two-column "menu on the left / preview on the right" feature browser.
 * Left: a vertical rail of feature tabs (icon + title), the first marked
 * .is-active with an accent left-bar + tinted surface. Right: the active
 * feature detail — large photo, small accent eyebrow (mirrors the active
 * tab title via shared binding), a static title and an expanded description.
 * Static (no JS): the first feature is always shown. Structurally distinct
 * from the horizontal tabbed-showcase (tabs-on-top) — here the tabs stack
 * vertically beside an illustrated detail panel.
 *
 * All selectors scoped to .universal-features--interactive-tabs-photo-static.
