What this fixture exercises

## A calendar that gets out of the way.

### Monochrome by design

Pure white canvas, charcoal (#242424) text, and a single link-blue. Boldness comes from contrast, not from color.

### Cal Sans speaks. Inter explains.

A custom geometric display face for headings, Inter for body. The font pairing enforces a clear typographic division — Cal Sans is never used below 16px.

### Shadows do the bordering

A multi-layer ring + contact + ambient shadow stack replaces CSS borders. Surfaces feel like physical cards sitting on a table — never floating, never flat.

Form components

## Get scheduling at the speed of Cal.

Inputs are minimal: hairline border, charcoal text, and the one link-blue makes its second appearance only on the focus ring — exactly where it earns its keep.
