+
+**Files Changed:**
+
+- `assets/css/admin.css` - Fixed tab gap, added subtab styles, booking form styles

+
+**Learnings:**
+
+- WordPress nav-tab styling expects tabs and content to be flush (no margin/gap)
+- Localhost detection should cover common development TLDs (.local, .test, .dev, .ddev.site)
+- Private IP ranges can be detected using `FILTER_FLAG_NO_PRIV_RANGE`
+- WordPress plugin updates require hooking into `pre_set_site_transient_update_plugins` and `plugins_api`
+- Subtabs can be implemented with query parameters and conditional rendering within a single settings callback
+- URL fields should use `esc_url_raw()` for sanitization, email fields use `sanitize_email()`
+- Always check if post object is valid (`$post instanceof \WP_Post`) before accessing properties - auto-draft causes issues
+- AES-256-CBC encryption with random IV provides secure storage for sensitive data
+- Store IV concatenated with encrypted data (IV is not secret, just needs to be unique)
+- `use_block_editor_for_post_type` filter disables Gutenberg per post type
+- Post types with `show_in_rest => true` get Gutenberg by default, which hides traditional meta boxes
+- Form-based admin interfaces (data entry) should use classic editor, not block editor

+**Files Created:**
+
+- `src/Api/RestApi.php` - Main API registration
+- `src/Api/RateLimiter.php` - Rate limiting
+- `src/Api/ResponseFormatter.php` - Response formatting
+- `src/Api/Controllers/AbstractController.php` - Base controller

+- Permission callbacks return bool; use `current_user_can('edit_posts')` for admin endpoints
+- Rate limiting with transients: store count and start time, check against limits
+- Transient key should include client identifier and endpoint type hash
+- X-RateLimit headers (Limit, Remaining, Reset) provide rate limit info to clients
+- Application Passwords (WordPress 5.6+) recommended for external API access
+- HATEOAS links added via `_links` key in response
+- Conflict detection reuses existing `Availability::check_availability()` method
+- Settings subtabs use query parameters (`subtab=general`) with conditional rendering
+- Configurable options should have sensible defaults via `get_option($key, $default)`
+- Marketing content (MARKETING.md) should be gitignored to keep repo focused on code
+
+**Released:**
