+<objective>
+Automatically crop uploaded job logos to 200x200px square for consistent display across archive and detail pages.
+
+Purpose: Ensure all job logos display at consistent size regardless of upload dimensions, preventing layout issues in Elementor templates.
+Output: WordPress image size registration that auto-generates 200x200px cropped version on upload.

+**Tech stack available:** add_image_size() WordPress function, ACF image field with return_format='id'
+**Established patterns:**
+- ACF image field returns attachment ID (Phase 01-03: job_logo with return_format='id')
+- Singleton pattern for post types class (Phase 01-02)
+- Image sizes available via wp_get_attachment_image_src()
+
+**Constraining decisions:**
+- Phase 01-03: Logo field returns image ID, not URL, enabling access to all registered sizes
+- Phase 01-03: Logo field optional (required=0) so not all jobs have logos
+- PROJECT.md: Logo auto-crop to 200x200px for consistent display
+- ROADMAP.md Phase 5: Logo upload and auto-crop to 200x200px

+  <name>Task 1: Register 200x200px cropped image size for job logos</name>
+  <files>includes/class-post-types.php</files>
+  <action>Add static method register_image_sizes() to DDHH_JM_Post_Types class. Inside method, call add_image_size('job-logo', 200, 200, true) - width 200, height 200, hard crop true (ensures square crop from center). Hook method to after_setup_theme action (priority 10) - this is standard WordPress timing for image size registration. Register hook in existing init() method or create new setup_hooks() method following singleton pattern if init() doesn't exist. This ensures WordPress automatically generates 200x200px version when logos uploaded via ACF field. Elementor templates can then request this size via wp_get_attachment_image() or wp_get_attachment_image_src() using size 'job-logo'.</action>
+  <verify>Check class-post-types.php contains register_image_sizes() method. Verify add_image_size called with parameters: 'job-logo', 200, 200, true. Confirm hook registered for after_setup_theme. Check method called from init() or setup_hooks().</verify>
+  <done>Image size 'job-logo' registered with 200x200px hard crop, hook properly registered for after_setup_theme, method integrated into class initialization</done>

+Before declaring plan complete:
+- [ ] Image size 'job-logo' registered via add_image_size()
+- [ ] Dimensions are 200x200px with hard crop enabled
+- [ ] Hook registered for after_setup_theme action
+- [ ] Method properly called from class initialization
+</verification>
+
+<success_criteria>
+
+- WordPress image size 'job-logo' registered and available
+- Uploaded logos auto-generate 200x200px cropped version
+- Size accessible via standard WordPress image functions
+- Elementor templates can use 'job-logo' size for consistent display
+- Phase 5 complete - mentor job board fully functional
