Radius

Squircle-leaning steps — softer and larger than a typical Tailwind kit.

Softer, larger steps than most systems default to — this is one of the things that makes Asteria not read as "generic Tailwind kit."

Where each step is actually used

Confirmed against the real Figma spec for every component built so far — not guessed:

  • radius-xs (6px) — checkboxes, dropdown/menu items, tooltips
  • radius-sm (8px) — buttons, inputs, textareas, alerts, badges
  • radius-md (10px) — dropdown/menu panels
  • radius-lg (14px) — modals
  • radius-xl (20px) — not yet used by any built component
  • radius-full (9999px) — pills, avatars, switches, radio/checkbox indicators

An earlier draft of this page (and of CLAUDE.md) suggested radius-md was for "inputs/buttons" and radius-xl for "modals" — neither held up once the real specs were pulled from Figma. Buttons and inputs are radius-sm; modals are radius-lg.
