- API key retrieval now trims whitespace (pasted keys with spaces caused auth failures)
- Fallback to Vue data property if localStorage is empty (covers forgot-to-save case)
- Auto-saves key to localStorage when found only in Vue data
- HTTP-level error handling (401/402/403) with clear user-facing messages
- Changed HTTP-Referer from window.location.origin to window.location.href
(origin returns "null" for file:// URLs, breaking OpenRouter requests)
- Handle non-JSON error responses gracefully
- Handle string-type error responses from OpenRouter
- Added missing else branch for empty API responses
- Updated README with AI Translation, PromptCraft, and OpenRouter key setup docs
