v2.3.0

Minor Changes

• f6acf80: Fill primary buttons with the action tokens and raise them with --cz-shadow-action

  Primary buttons read --cz-color-bg-action-solid,
  --cz-color-bg-action-solid-hover and --cz-color-text-on-action, so they
  stay gray while the brand hue marks selection. Their depth comes from
  --cz-shadow-action and --cz-action-sheen, so every primary button in the
  app is raised the same way. The link variant reads --cz-color-text-link.
  Requires @neovici/cosmoz-tokens 4.9.0.

• a28703f: Refresh the button look

  • Primary and destructive get a soft top sheen, a crisp edge and a small
    lift; secondary is a raised surface with a hairline border; tertiary
    hovers with a translucent wash that works on any background.
  • Labels are 13px at md with slightly tighter tracking, icons 16px (14px at
    sm, 18px at xl), and icons sit closer to the label.
  • Pressing scales the button down slightly instead of only darkening it
    (off with reduced motion).
  • Focus shows a 2px outline outside the button. Containers that clip
    overflow need at least 4px of room around the button.
  • Disabled buttons fade instead of turning gray, so they keep their variant.
  • Toggled secondary and tertiary buttons use a neutral translucent fill
    instead of the brand chip.

  Primary uses --cz-color-bg-brand-solid; it looks its best with the graphite
  fill from @neovici/cosmoz-tokens (Neovici/cosmoz-tokens#62).

  The link variant uses --cz-color-text-link (falling back to
  --cz-color-text-brand on older tokens), so links stay distinct from body
  text now that the brand ramp is gray.
