Compact light-first publication interface
- Changed the public default to a high-contrast light appearance while retaining a persistent visitor-controlled dark theme.
- Added an accessible header theme switch whose preference is stored only in the visitor’s browser.
- Reduced utility, header, publication-bar, hero, section, partner-banner, and footer spacing to remove unused vertical space.
- Shortened primary navigation labels to Start, Standards, Validate, Missions, Reports, and Policy so the menu remains on one line on common desktop widths.
- Retained the original 2048 × 682 partner advertisement artwork and proportional responsive scaling.
