Menu
The Menu button is at the top left. The drawer slides in. Escape or a tap on the dimmed page closes it. On a phone the same Menu is the left side of the bottom bar.
Course
Learn opens a ten-minute SIP path and the full course. Each room has a five-minute block, a drawing, a worked example, a quiz, and sources. Emergency calling and recording are study notes, not legal advice.
Bot
The monkey greets once after the tour, then sits at the right. Drag it. It can read the page aloud, take a typed question, or try the mic. Ambient sound is off until you turn it on. After a few quiet minutes it may offer help. Not now dismisses that offer. Stop offering keeps it quiet.
Downloads
Every room has SVG, PNG, HTML, and a cheat sheet. The Downloads page lists the deck, the cards, the templates, and one zip.
