From 19ae096acd8ef846c26c6235dd761d49f047c282 Mon Sep 17 00:00:00 2001 From: Joey Yakimowich-Payne Date: Tue, 21 Apr 2026 17:47:39 -0600 Subject: [PATCH] feat(chess/ui): add visual-builder BlockCard + PreviewPane foundations (T16, T17) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduces the presentational primitives of the upcoming visual-mode authoring surface, scoped so they can be dropped into an existing editor without touching form-mode logic. T16 — BlockCard (visual-builder/BlockCard.tsx): Single primitive-block renderer. Pure controlled component — no own state, no DnD. Props take node + index + isSelected + isExpanded + onSelect/onToggleExpand/onRemove + depth. Color-codes by kind: - blue: state primitives (seed/add/multiply/add-direction/set-capture-flag) - emerald: mechanic primitives (absorb/reflect/modify-range/block-move/ override-promotion) - violet: advanced/trigger primitives (auras + all on-* hooks + conditional) Accessible: role='article', keyboard-focusable, Enter toggles expand, Space selects, Delete/Backspace removes. Indent visually clamped at depth 3. Delegates parameter editing to ParamField when expanded. T17 — PreviewPane (visual-builder/preview/): Tabbed live preview with role=tablist semantics. Three sub-views: - NarrativeView — renders narrate(descriptor) in a semantic 
 for assistive tech
- JsonView — pretty-printed JSON with copy-to-clipboard (Sonner toast)
- BoardDiagramView — 8×8 SVG highlighting on-moved-onto-square filter
  squares and add-aura radii; shows 'No board effect' placeholder when
  the descriptor has no positional primitives

All sub-views memoized on descriptor identity. BoardDiagramView tolerates
in-edit malformed descriptors via structural unknown casts so the
preview doesn't throw during authoring.

Wave 3 will add BlockList (dnd-kit wrap around BlockCard) and
VisualBuilderPane (composition shell + palette + preview).
