ADDED Requirements

Requirement: System theme is default when no preference exists

The system SHALL default to system theme behavior if no persisted theme preference is found.

Scenario: No saved preference on first visit

• WHEN a user visits the site with no stored theme value
• THEN the UI resolves theme from system color-scheme preference
• AND switcher indicates system mode as active

Scenario: Persisted preference overrides system default

• WHEN a user has an existing stored theme preference
• THEN stored preference is applied instead of system mode
• AND user-selected theme remains stable across reloads
