/**
 * Optimize a mixed (real + int + categorical, with conditional) space. DISCRETE dims (categoricals + small
 * integers) are ENUMERATED as a combo grid (never interpolated); within each live combo, the active REAL /
 * large-int dims get a deterministic continuous search (space-filling seeds → golden-section coordinate
 * descent that PINPOINTS a smooth optimum, incl. the right integer). Budget is split fairly across combos
 * (a harder higher-dim combo seeds low and must NOT be discarded early), each search returns budget the moment
 * it converges, and any remainder concentrates on the current leader. Cost is BOUNDED and roughly linear in
 * the number of combos (≈ combos × sub-budget) — not an exponential explosion. Inactive conditional dims are
 * FROZEN (never searched), so no budget is wasted on a knob that does nothing right now. Honest: optimizing K
 * genuinely-distinct discrete configurations takes ~K× the continuous cost — the win is bounded + correct.
