Markback classroom pilot

1. Extract markback-pilot.zip. Keep the resulting markback folder on your computer.
2. Open Google Chrome and enter chrome://extensions in the address bar.
3. Turn on Developer mode, choose Load unpacked, then select the markback folder
   that contains manifest.json. Pin Markback from Chrome's extensions menu.
4. Open Markback Settings and enter your own Anthropic API key. Your key is stored
   locally in Chrome. API use is billed to your Anthropic account.
5. Open your school's Canvas SpeedGrader on a *.instructure.com domain. Select
   the correct submission, generate feedback, and review it before applying.

Markback drafts grades and feedback. A teacher must review the results and
choose whether to apply them to Canvas. It sends the submission text you ask
it to grade to Anthropic. Follow your school's policy for student data and AI.

This pilot ZIP is not a Chrome Web Store installation. A managed browser may
block unpacked extensions; ask your school IT administrator if loading fails.
Canvas sites with a custom domain are not supported by this build. Classic
Quizzes and assignment workflows have automated coverage; live Canvas and
managed school devices still need a teacher's check before classroom use.
