Hero Section Banner

A full-width hero skeleton with cinema presence: a massive banner slab breathing a dark aurora gradient, overlaid by centred headline, subline and CTA-pill placeholders swept by a wider, softer shimmer. This is the loading state for landing pages where the hero IS the first impression — it must feel designed, not broken.

## JavaScript
```js
/* No JavaScript — a slow aurora drifts on ONE big element while translucent bars sweep with the standard translateX shine. */
```

How this works

Two independent loading signals layer up. The banner base is an oklch aurora — three radial lobes drifting on a slow background-position loop (one large element, paint-cheap) — while the content placeholders use the standard .ssc-sk translateX sweep with a wider 40%-band gradient so the shine feels proportional to the hero's scale.

The overlay bars are semi-transparent white so the aurora glows through them — the "lighter centred shimmer" pattern classically paired with hero skeletons. Everything is centred with grid place-items, and the banner reserves a fixed min-height (here 280px, or a viewport unit in production) so the page's above-the-fold geometry never shifts.

Make it yours

  • Size with viewport units in production (min-height:60vb) — the skeleton must reserve the same fold as the real hero.
  • Re-weather the aurora by rotating the three oklch hues.
  • Left-align the content stack for editorial heroes.
  • Slow the aurora (--drift) for calmer brands.

Gotchas — read before shipping

  • The aurora animates background-position on ONE big element — never replicate that on many small bars; keep them transform-only.
  • Reserve the hero's real height including padding, or everything below shifts when it mounts.
  • Keep overlay bars translucent; opaque bars over a dark banner look like censor strips.

oklch is the modern piece; the layered gradients and shimmer run on any evergreen engine.
