Every account gets a profile card from sign-up: your picture, name, @username, rank and progress, and your profile link, in light or dark. Download it as a PNG from the Dashboard or your profile's Share button; it updates as you learn. Pick a cover in Dashboard → Profile (circuit, Bloch sphere, waves, qubit grid, aurora) or upload your own; it shows on your page and your card. Sharing your /@username link now previews your own card instead of the site's.
The git prompt in the Playground Terminal now asks you to sign in and connect GitHub first, with a Connect GitHub button right there. Running code while signed out says “Sign in needed” instead of a technical error.
Quality pass over every page and API: a proper 404 page (with a real 404 status for unknown lessons and chapters) and an error screen with Try again, better contrast and screen-reader labels in light and dark mode, and a fixed search link to the OpenQASM chapter.
Community → Articles: every Public article from all learners in one place, newest first, with search and tags (reading only: no likes or comments).
The sample profiles' articles now appear on their own when the site starts, so there is nothing to press.
Download an article as a PDF in its own style (made on the server with the same page readers see), and a circuit as an animated GIF that adds one column at a time, with an optional probability bar, speed and loop.
New article block: Bloch spheres and probabilities after each gate of your circuit (up to 5 qubits), with a step slider.
Report button on public articles, circuits and results. Reports reach the administrators, who can hide content; hidden content stays private until restored.
Profiles and articles: a Public article stays readable by its link even when your profile is private. You can switch your profile between Public and Private on your own profile page, and Community cards show how many articles each person published.
The sample (demo) profiles now have real articles, clearly marked Demo: superposition on the Bloch sphere, Grover's search, noise on a Bell state, the 3-qubit bit-flip code, the surface code's parity checks, a variational (QML) circuit, fault tolerance and GHZ. Their results come from real simulator runs.
