X_UI_INVALID_VALUE
Means
@ultimat3/ui received a value it cannot use
Typical cause
NaN money or an invalid date reaching a formatting component; upstream icon data the glyph generator refuses — a body that is not JSON, a node that is not [tag, attributes], an attribute value or icon name off the allowlist; or — as a Sass @error — t.rem() / t.fluid() given a unit other than px or rem, t.fluid() given a viewport range that is empty or reversed, respond-between given $from at or above $to
Fix
fix the value upstream; formatting never guesses, and the icon generator never emits data it could not validate — data the pinned version published is bun run --filter @ultimat3/ui icons --bump, which moves LUCIDE_VERSION to the latest release and regenerates. A Sass refusal carries the literal replacement in its own fix: — write respond-between("md", "lg"), pass a px length, e.g. rem(24px)
