- Add skill complexity budget system with base costs per skill type: - Basic skills: 0 (trivial bead movements) - Five complements: 1 (single mental substitution) - Ten complements: 2 (cross-column operations) - Cascading operations: 3 (multi-column) - Add per-term complexity debug overlay in VerticalProblem (toggle via visual debug mode) - Shows total cost per term and individual skill costs - Highlights over-budget terms in red - Make session structure parts toggleable in configure page: - Can enable/disable abacus, visualization, and linear parts - Time estimates, problem counts adjust dynamically - At least one part must remain enabled - Fix max terms per problem not being respected: - generateSingleProblem was hardcoding 3-5 terms - Now properly uses minTerms/maxTerms from constraints - Set visualization complexity budget to 3 (more restrictive) - Hide complexity badges for zero-cost (basic) skills in ManualSkillSelector 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
