## Source Review

- **Review date**: 2026-05-24
- **Source**: https://www.polymarketimes.com/
- **Fetched title/evidence**: Will Russia capture Lyman by December 31, 2026?... - The Polymarket Times
- **Fetch status**: Fetched https://www.polymarketimes.com/ with status 200; prompt-guard scan returned CLEAN.
- **Observed source colours**: `#F4F1EA`, `#1A1A1A`, `#000`, `#FFF` from fetched HTML/CSS.
- **Screenshot evidence**: user-provided screenshot shows cream newsprint background, black ticker/nav bars, green up-market indicators, red down-market indicators, Playfair Display masthead/headlines, Georgia article copy, and Menlo market/ticker UI.
- **Observed content cues**: masthead "The Polymarket Times", late city edition timestamp, all-caps section navigation, market ticker, category lozenges, thick horizontal rules, monochrome imagery, dotted table/list separators.
- **Rule**: source facts and user-provided screenshot inform the DESIGN.md; renderer tokens are adjusted for report readability, local font fallbacks, and WCAG contrast.
