+	 *
+	 * Inspired by Figma's right panel: the same UI slot shows different
+	 * controls depending on what the user is editing.
+	 *
+	 * Contextual modes (derived from snippetProps):
+	 *  - 'default'  → outline + word/char/reading time + writer warnings
+	 *  - 'format'   → bold/italic/underline + link + align (text selected)
+	 *  - 'image'    → alt/caption + alignment + status (in image)
+	 *  - 'table'    → row/col ops + header + striped + tone (in table)
+	 *  - 'code'     → language picker (in code block)
+	 *  - 'list'     → kind toggle + indent (in list item)
+	 *
+	 * This is the spike-1 surface (commit DRAWER-1): shell, context
+	 * detection, default panel only. Contextual panels arrive in
+	 * DRAWER-2.
