0.29.0 — Image zoom-on-hover and a single slot-prose pin

Added

• Images can zoom their contents on hover. Image gains an optional zoom
  prop and a global "Use zoom" editor intrinsic (the same gate-var + tri-state
  pattern as Card hover): zoom={undefined} inherits the editor default,
  true/false force one instance on or off. The frame stays fixed; only the
  <img> scales, via transform: scale(var(--image-zoom-scale)) with a
  --duration-300/--ease-out-cubic transition. CardEditor and ImageEditor
  now export intrinsics, registered in the component registry.
• --scale-{sm..2xl} transform-multiplier scale in tokens.css (1.05 → 1.25,
  5% per step), consumed by the image zoom above and surfaced in the editor as
  the SCALE variant. Ships with a paired tokens.css migration
  (2026-06-03-transform-scale-additions): run npx live-tokens migrate to add
  the scale to a vendored tokens.css, or the picker shows a blank slot for
  --image-zoom-scale.
• check:slot-prose publish gate. Fails the build if a slot-rendering
  component hand-rolls the slot-typography pin (a :global(p|ul|ol|li) rule set
  to the literal inherit) instead of @include slot-prose. Added to
  prepublishOnly.

Fixed

• Consumer global element rules no longer repaint slotted content. Components
  render the consumer's raw HTML in the same light-DOM tree, so a consumer's
  global p / ul li rules (for example in site.css) matched slotted elements
  and beat the container's body typography (the serif-card bug). The pin now
  lives in one place, src/system/styles/_slot-prose.scss, applied via
  @include slot-prose on Card, CollapsibleSection, and Image. Three
  diverging hand-copies had shipped before; check:slot-prose keeps them out.

Changed

• The slot-prose pin is per-axis, not font: inherit. It pins only the axes
  a component owns (family, size, weight, line-height, colour, plus spacing
  rhythm) and leaves font-style, letter-spacing, and text-transform free,
  so a consumer's italics or tracking survive inside a card or section.
• Card and CollapsibleSection gain a prose prop (default true). Set
  prose={false} to drop the pin and fully own slotted-content styling.
• fonts.css (generated from the production theme) swaps Fraunces for Manrope.
