Input

Recipe CSS

This is the exact CSS your kit ships for Input — token-driven, so it re-themes with every knob. Get it (and the rest) from the configurator's Use kit panel.

/* === Form ===
 * Inputs follow Stature: Compact = 32px (Linear/Cursor feel), Balanced = 40px

   * --k-field-bg is transparent in Plain. The border is set on all sides via
   * --k-field-border-color (input-border in Outlined, transparent in Filled +
   * Plain) and the BOTTOM is overridden to --k-field-underline-color — so Plain
