Dashboard.module.css mixed base shell styles with the entire scan terminal surface, making every decision-card or calendar styling pass risky. This extracts the scan terminal layer into its own CSS module and attaches that module root beside the existing dashboard root so global class selectors keep their current behavior.
Constraint: Preserve existing global scan-* class names and visual cascade.
Rejected: Rename scan classes into scoped module keys | too much DOM churn for a behavior-preserving CSS split.
Rejected: Split card/calendar/mobile rules in the same pass | safer to establish the scan-terminal layer first before finer component CSS ownership.
Confidence: high

Not-tested: Pixel-level browser comparison across dark and light themes.
Users needed reassurance that unavailable quotes and long AI evidence are normal states, not broken systems. This adds a v1.5.5 upgrade announcement, softens market-unavailable copy, surfaces a one-line recommendation reason, and makes mobile cards prioritize observed temperature, expected high, peak timing, AI expansion, and a separate market line.
Constraint: Keep existing dashboard data contracts and avoid backend schema changes.
Rejected: Hide unavailable market rows entirely | users still need to know weather evidence remains usable without a quote.

Users need to know whether a city can be acted on before reading the full explanation. City cards now expose METAR or official-observation freshness, model update timing, market quote freshness, and AI state in a dedicated trust block, while the calendar view groups rows into action-oriented timing buckets with a single reason per city.
Constraint: Keep the existing card and calendar data contracts; derive freshness and action reasons from fields already present in the frontend payload.
Rejected: Add another long explanatory paragraph | it would repeat the same trust problem instead of making the first glance clearer.
Confidence: high
Scope-risk: moderate
Reversibility: clean
Tested: npm run build
Not-tested: Live browser visual QA with stale METAR and delayed quote examples.
City decision cards already had enough evidence, but the first screen still forced users to read the longer explanation before seeing why a card mattered. The header now caps status chips at three high-priority signals and uses product-facing labels for observed breakouts, stale METARs, AI loading, missing market prices, strong model agreement, and next-report waits.
Constraint: The card should stay lightweight and avoid another explanatory section.
Rejected: Keep six mixed freshness chips in the header | too much noise for first-glance scanning.
Confidence: high
Scope-risk: narrow
Reversibility: clean
Tested: npm run build
Not-tested: Browser visual QA across all city states.
The decision card now exposes deterministic guard state, data freshness, AI readiness and market sync directly in the card header so users can understand whether they are looking at fresh evidence, a fallback, or a stale/exception case before reading the full explanation.
Constraint: Keep the first useful read available while DeepSeek airport/HKO details are still streaming.\nRejected: Add another expanded evidence panel | header-level badges are faster to scan and avoid increasing card depth.\nConfidence: high\nScope-risk: narrow\nReversibility: clean\nTested: npm run build\nNot-tested: Browser visual QA on production data.
