- The three market Content Blocks preview as compact collapsible rows:

thumbnail of the actual image (hero background, intro image, insights
  cover), key copy in the summary line, full details expanded; card and
  intro-paragraph previews are wrapped in the same mechanism
- New SubmarketPluginPreview for vitec_usecaselist / vitec_productfeature /
  vitec_productlist: instead of bare standard boxes they now list the
  selected story titles (flagging stories that still lack a quote), the
  featured product and the hand-picked products in order
- Container-style collapse for whole page-module COLUMNS: a chevron at the
  right of every column header folds a section down to its title row,
  state kept per page and colPos in localStorage - the slot view of a
  sub-market page folds to six slim bands
- Previews sit under the page module's pointer-events lock and its
  click-to-edit layer: pointer events are re-enabled inside the collapse
  markup and the toggle runs on pointerdown in the capture phase
- Two more v14 removals fixed on the way, both latent in the OLDER preview
  classes too (Usecaseshow, Modelcard would have crashed the page module):
  GridColumnItem::getRecord() now returns a Domain\Record object, and
  StandaloneView is gone - previews normalize the record via a shared
  helper and render through the ViewFactory
