+## From the 12 Sep screenshots — the exam player and what surrounds it
+
+The reference is UWorld-style for the exam player and AMBOSS for analysis.
+
+### Exam player chrome
+- [ ] **Top bar**: `Item: n of m` / `Block: 1 of 1` at the left, Previous / n of m
+      / Next in the middle, Lab Values · Notes · Calculator · Settings at the
+      right.
+- [ ] **Bottom bar**: `Block Time Remaining: 00:01:29` at the left, Pause and
+      Lock in the middle, End Block at the right.
+- [ ] **One button, not two.** A question with no answer offers Skip *and*
+      Next today. It is one boxed control: one button.
+- [ ] **Proceed to Next Item on the last question ends the block** rather than
+      doing nothing.
+- [ ] **Cross out an option** from a per-option control beside it (the `ab`
+      strike icon), not only from a menu.
+- [ ] **Pause says "Exam Paused" and nothing else** — a title and a Return to
+      exam button. No warning about real exams; that is AMBOSS's disclaimer,
+      not ours.
+- [ ] **End Session is a plain confirmation** — "Are you sure you want to end
+      this session?", End Session / Cancel.
+- [ ] **Right-click removes a highlight**, and the yellow itself needs fixing.
+- [ ] **The rail shows numbers while sitting an exam and shortened stems in
+      review.** It is numbers in both today.
+
+### Analysis
+- [ ] **Session Analysis is the third tab**, inside the Analysis page with the
+      session rail beside it — not a link away. Four figures, the donut, and
+      Study recommendations under Articles / Disciplines / Systems.
+- [ ] **An unfinished session shows Resume**, with the figures reading `--`
+      rather than a blank card.
+- [ ] **Knowledge profile paginates** (`1 – 10 of 20`) and each row expands to
+      two bars — questions completed, answered correctly split
+      correct / correct-using-hints / incorrect — with Read article and Start
+      Qbank beside them.
+
+### Elsewhere
+- [ ] **hCaptcha replaces Turnstile**, everywhere Turnstile is wired.
+- [ ] **The session rail scrolls** once it holds more than a screenful.
