## Core Architecture & Stealth Capabilities
- **0.3-Second Double-Click Inline Solve**: Double-tap any question on any LMS to solve instantly in place with zero tab-switching and zero copy-pasting.
- **Closed Shadow DOM Isolation (`mode: 'closed'`)**: Renders entirely inside an encapsulated closed Shadow Root with zero host DOM mutations, zero injected `<button>` tags, and zero exposed `web_accessible_resources` signatures.
- **Focus Shield Telemetry Cloaking**: Intercepts `window.blur`, `document.visibilitychange`, `focusout`, and `document.hasFocus()` polling so Canvas SpeedGrader and Blackboard activity logs record 100% continuous active focus (`0` tab-switch flags).
- **Snap-It Vision OCR (`⌘+Shift+S` / `Ctrl+Shift+S`)**: Draw a selection rectangle around locked text (`user-select: none`), organic chemistry structures, calculus integrals, physics diagrams, or embedded PDFs for instant multimodal vision solving.
- **Attempt Memory & Smart Cache**: Automatically records questions, selected choices, and feedback across multi-attempt Canvas and Moodle quizzes.
- **Emergency Panic Switch (`⌘+Shift+U` or `Esc × 2`)**: Completely unmounts the Shadow DOM HUD and flushes extension state from RAM in under 10ms.
- **Three Display Modes**:
  - *Invisible*: Silent answer delivery directly into the quiz with zero visual UI, popups, or toasts (100% screen-share safe).
  - *Stealth* (Default): Subtle micro-cursor indicator while reasoning, then seamlessly applies the answer.
  - *Explain*: Applies the answer and opens a step-by-step pedagogical explanation drawer.
- **Three Answer Delivery Methods**:
  - *Auto-fill* (Default): Selects the correct radio button, checkbox, or dropdown option using native human-paced input synthesis.
  - *Highlight*: Illuminates the correct choice with a subtle glow for 1–10 seconds (default 4s) so the student clicks it manually.
  - *Clipboard*: Copies the verified answer directly to the system clipboard for short-answer, fill-in-the-blank, and essay prompts.
