Constraint: Fix the visible regressions without changing the broader pricing model or image-studio backend contract.
Rejected: Ad hoc page-specific symbol patches | would leave model-pricing views inconsistent and fragile.
Confidence: high
Scope-risk: narrow
Directive: Keep model-pricing summaries on shared currency formatting and keep dynamic image-studio model controls fully controlled after save.
Tested: cd web && NODE_OPTIONS='--max-old-space-size=4096' npm run build
Not-tested: Browser-click verification on the live model plaza and image-studio settings form.
