- Team of Four hits for 28, 1 to 4 times, 95% of the time. Up to four students enter as one team, each adding an age, grade and school, or the word anonymous. Receipt: `OMMC-Test-Portal@f8c3b7eb2:src/portal/test.tsx:285-301,493-495,530-596; OMMC-Website@91ae7740f:src/Pages/Main.tsx:199-200`
- Problem Atlas hits for 80. Search past problems by text, topic and difficulty, then open each typeset solution when you want it. Receipt: `OMMC-Atlas@94847f913:src/Pages/Atlas/Atlas.tsx:23-44,68-105,126-220; src/Components/AtlasComponents/Question.tsx:9-34,42-67`
- Saved Locally restores 50 health. Each answer saves in the browser as you type and reloads from the server when you sign in, so nothing is lost. Receipt: `OMMC-Test-Portal@f8c3b7eb2:src/portal/question.tsx:19-24; src/utils/useLocalStorage.tsx:23-33; src/portal/test.tsx:79-103,109-155`
