Force fractions from the triangle: $\mu$ (EM-like), $\nu$ (gravity), $1-\mu$ (strong / relational friction). Mass gap = low-$\eta$ regime. ## Engine - Uses **`rst_engine.mu_rst(eta, n)`** and $\nu = (1-\mu^n)^{1/n}$ (three levels up). ## Output - **`yangmills_fractions.png`** — $\mu$, $\nu$, $1-\mu$ vs $\eta$.
