LabMnemora: Walk through what you want to remember

Mnemora is a 3D memory palace built on WebGL, where you place facts in a navigable scene and revisit them over time. The signature move is keeping the SM-2 spaced-repetition scheduler as a pure, framework-free module fully separate from the rendering, so the interval ladder, ease floor, and timezone-safe due dates can be unit-tested on their own. It is a from-scratch, dependency-light build you can download and run locally.
