dev	80b21f63ba	feat(eidos): port Listbox (embedded selection list) ... #131. Eidos wrapper + types + recipe + canonical-depth demo. Soma owns single/multi selection (value as string[]), roving-tabindex keyboard nav (Arrow + Home/End + typeahead + Ctrl+A), Field-merged flags (disabled/readonly/required/invalid), hidden form inputs. Eidos adds the visual surface and exposes variant + size + color. Reference parity (no air baseline — port directly from soma): | Feature | soma | react-aria | Headless UI | bits-ui | this port | |---|---|---|---|---|---| | Single + multiple selection | ✓ | ✓ | ✓ | ✓ | ✓ | | bind:value (controlled) | ✓ | ✓ | ✓ | ✓ | ✓ | | Typeahead + Arrow / Home / End | ✓ | ✓ | ✓ | ✓ | ✓ | | Loop nav | ✓ | ✗ | ✗ | ✗ | ✓ | | Section / Group + label | ✓ | ✓ | ✗ | ✓ | ✓ | | Ctrl+A select-all (multi) | ✓ | ✓ | ✗ | ✗ | ✓ | | Form participation (hidden inputs) | ✓ | ✗ | ✓ | ✗ | ✓ | | Field.Provider merge (disabled/invalid/…) | ✓ | ✗ | ✗ | ✗ | ✓ | | Horizontal orientation | ✓ | ✓ | ✓ | ✓ | ✓ | | Item indicator (✓ glyph) | ✓ | ✓ | ✗ | ✓ | ✓ shared partial | | Drag-to-reorder | ✗ | ✓ | ✗ | ✗ | ⚠ deferred | | Async / infinite loading | ✗ | ✓ | ✗ | ✗ | ⚠ deferred | | selectionBehavior (toggle/replace) | ⚠ implicit | ✓ | ✗ | ✓ | ⚠ deferred | | PageUp/Down nav | ✗ | ✓ | ✗ | ✗ | ⚠ deferred | Parts (5): Listbox (Root, replaces soma's Provider name), Item, ItemIndicator, Group, GroupLabel. Variant set: - variant: ControlVariant (`'surface' | 'outline' | 'ghost'`), default 'surface' - size: xs..xl (5-step canonical form-control scale) - color: ColorRole (primary/secondary/neutral/affirm/fulfill/risk/threat/loss) - block: stretch to container width Cross-component reuse: - `ItemIndicator` shares the menu-indicator visual (`a2709476`) — ✓ glyph identical to standalone Checkbox and Dropdown/Context Menu CheckboxItems. CSS-only difference: shown only inside `[data-listbox-item][data-selected]`. - Item row hover / highlight tokens mirror Combobox.Item / Command.Item — the form-control surface family stays coherent. Disambiguation note (in index.ts comment): - Listbox: atomic options, text rows, no inner interactive elements (ARIA forbids interactive descendants inside role="listbox") - GridList: rows with buttons / links / checkboxes inside (2D nav) - Select / Combobox: closed picker surface (Listbox-like dropdown) Gotcha: listbox.svelte and listbox-item.svelte rename `children` to `bodyContent` on destructure to avoid shadowing the inner `{#snippet children}` block (same recursion trap documented in `feedback_button_consumer_pattern.md` Rule 3). Demo: 6 tabs at canonical depth — Live wires all soma + eidos props, all 3 ControlVariant chips, 5 size chips, 8 ColorRole chips, single + multi mode toggle, RTL/horizontal toggle. Sidebar entry added under Forms (between Combobox and Calendar). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	5 months ago
