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, tooltipsradius-sm(8px) — buttons, inputs, textareas, alerts, badgesradius-md(10px) — dropdown/menu panelsradius-lg(14px) — modalsradius-xl(20px) — not yet used by any built componentradius-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.
