maturity: draft  priority: L

Summary: A bounded reference editor for five canonical field kinds, with keyboard ordering, local preview and explicit JSON definition import and export.

Use the pinned approved default profile. Pending roles in that profile use-and-report their decision IDs; this does not approve them. Proposed profiles are preview-only and blocked for delivery. Heritage profiles are historical-only. Deprecated or heritage roles are blocked for new approved-profile mappings. Consume roles within their documented scope, never primitives. Release numbering does not approve profiles or tokens.
Tokens (resolved):
  root.bg      #100c0c  ({color.surface.default})  use
  root.text    #e99499  ({color.text.default})  use
  root.border  #a3676b  ({color.border.control})  use-and-report (D-007)
  status.text  #bd787d  ({color.text.muted})  use
State dependency disclosures: D-007

States: default, empty, invalid, disabled

Keyboard:
  Tab / Shift+Tab: Reach add, field editor, ordering, removal, preview and transfer controls in document order.
  Enter / Space: Activate the focused native button. Move up and Move down preserve stable identity and focus.
  Arrow keys: Use native select and radio choices in the preview.

ARIA: Native buttons, labelled inputs, fieldsets and ordered field definitions; no drag-only operations.
Responsive: One column at narrow widths; editor controls and buttons wrap without changing order. Preview supports compact and comfortable density in the default profile.
Portability: A local reference implementation using existing field contracts. JSON is a theme-pinned definition, not an executable form or backend API.
  native: No native port or production form platform is claimed.

Rules: use only these values; no invented colours; radius 0; borders 1px (2px emphasis); focus is a 1px dashed ring, selection is a fill;
do not restyle unrelated elements; report deviations per agents/consume.md; record theme.lock.json at the pinned revision.
