Give Preview checkboxes their pointer-free path via the system focus model

10 promised toggleable-without-pointer, 11's normative inventory had the toggle as pointer-only, and 02's lock disabled it "via menu validation" with no menu item to validate. Settled: checkboxes and links are real controls in the focus/accessibility tree — FKA + Space and VO-Space toggle them; in-content controls are content, not commands, so 04's menu-item contract and 11's existence rule scope to commands; under the read-only lock the controls disable in place.

 - Renders headings, bold/italic/code, bullet/ordered/task lists, fenced + indented code, nested quotes, GFM tables (per-column alignment, columns sized to contents with the browser sizing rule), thematic breaks, HTML shown **verbatim as literal code-styled text** (never interpreted — no web view, per 00-vision.md's no-web-tech stance), and images resolved against the card's own folder (`![](attachments/shot.png)`).
 - **Remote images are never fetched** — Preview does no networking (sandbox-quiet, files-first). An `![](https://…)` renders as a quiet placeholder chip carrying the alt text (or the URL); the file-relative form above is the supported image story.
- **Task-list checkboxes are live**: clicking a `- [ ]` / `- [x]` checkbox flips exactly that marker in the source — a single-character textual edit; every other byte of the body is untouched. This is the deliberate exception to "Preview only reads": checklists are kanban's working currency, and a mode flip to tick a box is ceremony. A toggle is an ordinary user edit — the standard atomic write, auto-committed and undoable on git boards.

This is the deliberate exception to "Preview only reads": checklists are kanban's working currency, and a mode flip to tick a box is ceremony. A toggle is an ordinary user edit — the standard atomic write, auto-committed and undoable on git boards. **The pointer-free path is the system focus model** (settled): checkboxes — like Preview's links — are real controls in the keyboard-focus and accessibility tree, so Full Keyboard Access Tab-reaches them and Space toggles, and VoiceOver toggles with VO-Space (10-accessibility.md's real-accessible-checkboxes promise, honored natively). Without FKA they are not in the key loop — standard macOS content behavior, so ordinary Tab users never wade through a long checklist. In-content controls are *content*, not commands: no menu item, no chord — 04's every-function-has-a-menu-item contract covers commands, and 11-command-nexus.md scopes them accordingly. Under the read-only lock (02-architecture.md) the controls disable in place — the one mutating path menu validation can't reach.
 - Links: external URLs open in the browser; relative links open the target file with its default app (resolved against the card folder, like images).
 - **Edit ▸ Find (⌘F) is find-in-text here** — the standard find bar over the focused body surface (Preview's selectable text, the Edit editor, raw source); board search is a board-window concern (04-interactions.md ▸ Search).
