v0.1.3

Added

• Dark mode: a light/dark toggle lives at the bottom of the left rail and
  is remembered between runs.
• Visible Admin toggle in the rail (Ctrl+Shift+A still works).
• Wizard step indicator: numbered progress pips across the top of the flow.
• Design editor: edit the words directly, pick lettering styles rendered in
  the real bundled fonts, choose carve depth, tilt and center elements, and
  add art from a searchable gallery with big previews.
• "Carve a photo": pick a picture and Chip traces it into carvable shapes
  (grays out gracefully on machines without a working tracer).

Changed

• Full visual refresh: design-token theme system on Qt's Fusion style
  (consistent rendering on every platform), modern buttons/inputs/cards,
  branded rail, polished Home cards, and true-to-font canvas previews via
  the bundled TTFs.
• Wizard pages scroll when the window is small — the STOP bar can never be
  pushed off screen.
