canvas: Visual Reference Layer

The three knowledge capture layers:

• /save → text synthesis (wiki/questions/, wiki/concepts/)
• /autoresearch → structured knowledge (wiki/sources/, wiki/concepts/)
• /canvas → visual references (wiki/canvases/)

A canvas is a JSON file Obsidian renders as an infinite visual board. This skill reads and writes canvas JSON directly. Read references/canvas-spec.md for the full format reference before making any edits. This spec aligns with the JSON Canvas open standard.

Substrate preference (v1.7+): This skill is a self-contained fallback. Prefer kepano/obsidian-skills as the authoritative substrate — its json-canvas skill is the canonical spec reference. If you see a json-canvas skill available without the claude-obsidian: namespace, that is kepano's version: use it for spec questions. Continue to use this canvas skill for the wiki-scoped workflows (positioning into wiki/canvases/, /banana integration, zone layout) — those are unique to claude-obsidian and live above kepano's primitive. Install kepano: claude plugin marketplace add kepano/obsidian-skills.
