v2.1.34-fork.11

• Customize Theme has Background colors: 2 to 4 colors blended from top
  to bottom under the cards, as Aurora's. Editing a copy of one of
  Kero's themes starts with its own
• The Accent is now two colors: Highlight, for icons, outlines, links
  and the faint washes of selected rows, and Highlight background, for
  primary buttons, highlighted menu rows and pills. Text on Highlight
  background is white or near-black, whichever reads better, so Kero's
  dark themes now show dark text on their light blue buttons. A theme
  saved with an Accent takes it as both
• Each of these colors and the Background glow follows the theme until
  you change it: the highlight follows the cursor, the glow the
  highlight background
• Export copies the theme as the text of a Ghostty theme, Kero's colors
  too; Import… pastes one into the theme being edited, saved only when
  you click Save
