The dashboard had several oversized orchestration, component, and CSS files that made product-copy changes and mobile/performance work risky. This refactor preserves behavior while splitting scan terminal CSS, opportunity helpers, future forecast panels, history/detail charts, and probability/model sections into smaller ownership boundaries.
Constraint: No user-visible version bump because this batch is architecture and performance cleanup, not a release announcement.
Rejected: Rewrite dashboard state management in the same batch | too broad for a safe upload after CSS and component splitting.
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep new component/CSS boundaries instead of moving product copy back into the large dashboard files.
Tested: npm run build; npm run test:business; git diff --check
Not-tested: Browser visual smoke test after push
