 2. Right-click the image and choose **🔍 Select & Translate Region**.
 3. Draw a rectangle around the text you want translated.
 4. Review the translation in the overlay and adjust as needed.
 
 ### Overlay controls
 
 - **Analysis toggle**: enable/disable scene analysis.
 - **Retry**: re-run translation if text was missed.
 - **Style dropdown**: choose a style profile (Explicit, Literal, Localized, Erotic, Crude).
 - **Settings**: open the settings menu to change server URL, language, and model tuning.
 - **Global instructions**: apply instructions across all tabs until restart.
 - **Context badge**: view stored page context and history.
 
 ### Per-line actions
 
 - Right-click a translated line for Standard / Literal / Natural retranslation.
 - Add a note to a line to auto-retranslate with the note applied.
 
 ## Configuration
 
 Key settings live in the overlay **Settings** menu (⚙) and are persisted:
 
 - `LLAMA_SERVER`: server URL (default `http://127.0.0.1:8033`).
 - `TARGET_LANG`: output language (default `English`).
 - `MAX_TOKENS`, `TEMPERATURE`, penalties: model tuning values.
-- `IMG_MAX_DIM`: max size for image preprocessing.
 
 You can also edit prompt text and style profiles inside `background.js`.
 
 ## Permissions
 
 The extension requests:
 
 - `contextMenus` (to add translation options in right-click menus)
 - `activeTab`
 - `webRequest` and `webRequestBlocking` on `<all_urls>` (used to inject a Referer header when fetching images)
 
 ## Limitations
 
 - Manifest V2 is deprecated in Chromium; Firefox still supports it.
 - The extension assumes a local `llama.cpp` server is running with a vision model.
 - Some sites block cross-origin image fetching; translations may fail if the image is not accessible.
 
 ## Troubleshooting
 
 - **Cannot reach llama.cpp**: Start your server and confirm it listens on `127.0.0.1:8033`.
 - **Blank or missing translations**: Use **Retry** or check server logs for model errors.
 - **Region translate does nothing**: Confirm the image is accessible and not blocked by CSP/hotlinking.

 1. **Region translation is message-driven**: content must send `translateRegion`; background owns crop encode + pipeline execution. Source: `content.js` (`startSel`), `background.js` (`browser.runtime.onMessage` -> `translateRegion`).
 2. **Pipeline order is analysis-before-translation** when analysis is enabled. Source: `background.js` (`streamTranslation`).
 3. **Streaming output is sanitized**: strips `<think>`, removes `/no_think`, dedupes repeated blocks, optional SFX filtering if enabled. Source: `background.js` (`stripThink`, `cleanOutput`, `dedupeOutput`, `filterSfxBlocks`, `streamTranslation`).
 4. **History updates are image-aware**: retry may replace last entry for same image; new image pushes a new entry; history capped to 10 entries. Source: `background.js` (`replaceLastHist`, `pushHist`, `MAX_HISTORY`, `streamTranslation`).
 5. **Retroactive edits require strict JSON plan and safe application**; invalid/non-JSON is ignored. Source: `background.js` (`requestRetroactiveEditPlan`, `applyRetroactiveEditPlan`, `isHistoryEntrySane`, `retroactivelyUpdateHistory`).
 6. **Per-line note behavior**: Enter (without Shift) blurs/submits note path; line note changes debounce and can trigger retranslation + note persistence. Source: `content.js` (note input handlers in `render`), `background.js` (`retranslateEntryWithNote`, `addUserNote`).
 7. **Region-selection cancel uses Escape**. Source: `content.js` (`bindOverlayKeys`, `startSel`).
 
 ### Intended invariants (should not be broken)
 - Keep background/content message actions backward compatible for existing UI flows. Source locations to verify: `background.js` (`browser.runtime.onMessage`) and `content.js` (`browser.runtime.onMessage`).
 - Do not broaden extension permissions unless strictly required. Source baseline: `manifest.json` (`permissions`).
 - LLM edit plans for retroactive context remain strict JSON-only and are ignored if malformed. Source: `background.js` (`requestRetroactiveEditPlan`).
 - Avoid duplicate translated entries in final output. Source: `background.js` (`dedupeOutput`).
 
 ## B) Storage schema
 
 ### Persisted (`browser.storage.local`)
 Stored key: `settings` object. Source: `background.js` (`loadSettings`, `setSettings`, `resetSettings`).
 
 Current normalized fields (with defaults in `DEFAULT_SETTINGS`):
 - `LLAMA_SERVER` (string)
 - `TARGET_LANG` (string)
 - `MAX_TOKENS` (number)

 - `PRESENCE_PENALTY` (number)
 - `DRY_MULTIPLIER` (number)
 - `DRY_BASE` (number)
 - `DRY_ALLOWED_LENGTH` (number)
 - `DRY_PENALTY_LAST_N` (number)
 - `LOOP_THRESHOLD` (number)
 - `RETROACTIVE_CONTEXT` (boolean)
 Source: `background.js` (`DEFAULT_SETTINGS`, `normalizeSettings`), UI exposure in `content.js` (`openSettingsModal`).
 
 ### In-memory only (per current code)
 - `globalInstructions` (cross-tab until restart). Source: `background.js` (`globalInstructions`, `setGlobalInstructions`/`clearGlobalInstructions`).
 - `tabState[tabId]`, `pageHistory[tabId]`, `storyRegistry[tabId]`. Source: `background.js` (same-named objects + `browser.tabs.onRemoved`).
 - TODO: confirm whether any of these should be persisted across restart (currently they are not).
