Render pipeline:
- Replace per-object _apply_smooth() loop with _apply_smooth_batch(): selects
all 175 parts, calls shade_smooth_by_angle() ONCE in C → reduces 16s to ~0.2s
- Remove 175 per-part "assigned material to part" log lines (replace with summary)
- Add TIMING_SUMMARY log line at end of every render showing all step durations
- _lap() helper records split times for: template_load, glb_import, rotation,
smooth_shading, material_assign, pre_render_setup, gpu_render
Frontend role checks:
- Add global_admin + tenant_admin to User role type in auth store
- Add isAdmin() and isPrivileged() helper functions
- Fix Admin.tsx, Layout.tsx, Notifications.tsx, OrderDetail.tsx, ProductDetail.tsx,
CostOverviewWidget.tsx — all were checking role === 'admin' but JWT now has
role === 'global_admin' after migration 049 (admin → global_admin backfill)
- This caused Admin page to render completely empty
