v2.0.0

Major Changes

• 781aeb4: BREAKING fix: require @neovici/cosmoz-tokens ^4.2.0

  Pressed styles use light-dark() directly, which only resolves with
  tokens v4's color-scheme-driven theming, and consume the
  --cz-shadow-pressed-3d(-solid) inset tokens added in 4.1.0. Also
  requires @neovici/cosmoz-tooltip ^1.4.0, which supports tokens v4, so
  the dependency tree can resolve a single tokens copy.

Minor Changes

• 781aeb4: Add icon-only mode (Untitled UI utility button)

  The icon-only attribute renders a compact square button (28–40px
  across sizes) with a muted icon color for the quiet variants
  (secondary/tertiary).

• 781aeb4: Redesign the pressed/selected state (aria-pressed)

  • secondary and tertiary shift to a selected brand chip (dark:
    brand-900 with brand-300 text); secondary keeps a visible inset
    ring
  • primary and destructive stay solid with a 3D inset sink; hover
    matches the non-pressed solid pair
  • link: underline only, no surface change
  • icon-only pressed icons take the chip color (lighter on dark hover)

• 781aeb4: Add tooltip support

  tooltip wraps the button in cosmoz-tooltip with the heading;
  tooltip-placement positions it (top, bottom, left, right). The wrapper
  is always rendered and degrades to a pass-through when tooltip is
  unset, so host-driven sizing keeps working.
