## JavaScript
```js
/* No JavaScript — a min-height:100dvh grid with 1.1fr/1fr tracks; each half centers its content with place-items, and the brand panel compresses to a banner on mobile. */
```

How this works

The wrapper is a grid with min-height:100dvh — the dynamic viewport unit that tracks mobile browser chrome correctly, where 100vh famously overflows behind the URL bar. Tracks are 1.1fr 1fr: near-equal, with a hair more room for the brand story.

The brand half layers a gradient mesh (three radial gradients) with a subtle grain via repeating-conic-gradient, all in the background stack — zero images, instant paint. Each half centres its content independently with display:grid; place-items:center. At 780px the grid stacks and the brand panel compresses into a short header band so the form stays above the fold.

Make it yours

  • Rebalance the halves with the fr values (1.5fr 1fr gives a dominant brand side).
  • Swap sides by reordering the two children — or keep DOM order and use order for the visual flip.
  • The mesh is three radial-gradients: move their at x% y% anchors to art-direct the glow.
  • For a photo background, replace the gradient stack with image-set() + an oklch overlay via background-blend-mode.

Gotchas — read before shipping

  • Use 100dvh, not 100vh — on iOS Safari 100vh includes the collapsed URL bar and your CTA slides off-screen.
  • Don’t fix BOTH halves’ heights; let the form side grow — password managers and autofill banners add unexpected height.
  • Keep form inputs ≥16px font-size on mobile or iOS zooms the viewport on focus.

Floor set by oklch(), color-mix(), backdrop-filter, text-wrap as this demo is written. The core technique itself goes back further — Chrome 108+.

Versions are for dvh units; with a plain 100vh fallback line (included) the layout works in anything that has grid.
