/* ─────────────────────────────────────────────────────────────────────
	FEATURED WORK SECTION
	─────────────────────────────────────────────────────────────────────
	Home-page below-the-fold credibility band. Markup lives in
	`src/_includes/partials/featured-work.njk` and the single-card macro
	in `featured-work-card.njk`. Data source: `collections.featuredCaseStudies`
	(filters `is_featured: true`, sorts by `weight` ascending).

	Card model: `<article>` root with an absolutely-positioned thumbnail
	that holds a gradient-blob "image" layer, always-visible badge +
	arrow indicators, and a translucent hover overlay containing the
	eyebrow + title + tech chips. The whole card is clickable via the
	stretched-link pattern on the overlay-title anchor (a `::after`
	pseudo-element covers the card area).

	On hover:
		• `.innov8-fw-thumb-image` scales 1.06× (revealing more of the
			eventual screenshot — currently the gradient placeholder).
		• `.innov8-fw-thumb-overlay` fades in from opacity 0 → 1,
			darkening the image and surfacing the title content.
		• Badge fades out; arrow tints cyan + scales slightly.

	Layout: full-bleed 3×3 grid, gap: 0, edge-to-edge (no container
	constraint, no inter-card gutter) — matches Mike's prior-site UX
	where the card mosaic spans the viewport edge to edge.

	All class names use the `innov8-fw-` prefix (mirrors the
	`innov8-hero-` / `innov8-nav-` convention from prior partials so
	the section-scoped rules can't accidentally collide).
