 Prompt preset storage — reusable prompt snippets scoped by model classification.
 
 Two layers:
-  System: data/prompts/*.json — shipped preset packs (read-only)
-  User:   {user_dir}/PromptChain/prompts/*.json — user-created presets
+  System: data/prompts/**/*.json — shipped preset packs (read-only)
+  User:   {user_dir}/PromptChain/prompts/**/*.json — user-created presets

-all files are ingested and merged. User prompts with the same `id` override
+Each file contains a list of prompts. Files may be organized into subdirectories.
+All JSON files are discovered recursively and merged. User prompts with the same `id` override
 system prompts. Prompts are filtered by scope against the current model's
 architecture, family, version, or exact hash.
