### block.json Fields (Consistent Across All)
```json
{

  "apiVersion": 3,
  "name": "im-press/[block-name]",
  "title": "[Display Title]",
  "category": "im-press",
  "icon": "[dashicon]",
  "description": "[Short description]",
  "keywords": ["keyword1", "keyword2"],
  "textdomain": "im-press",
  "attributes": { ... },
  "supports": { "html": false, "align": ["wide", "full"] },
