A black-and-white design system, on purpose

The interface has no accent colour. Links, active states and primary buttons are all the same near-black. That is a deliberate constraint, not an unfinished theme.

Why: the moment you introduce a brand colour, every component competes for it. Buttons become the loudest thing on the page, which is backwards for a tool — the content is the point.

How hierarchy is expressed instead: weight, spacing, and contrast. A primary action is a filled dark rectangle; a secondary one is a thin border; a tertiary one is underlined text. Three levels are enough for almost everything.

Where it hurts: error states. Destructive actions currently use the same monochrome treatment, which can under-signal danger. We are watching whether that is a real problem in practice before adding a second colour for it.

Rounded corners and a single border weight do a lot of the remaining work.
