+## ADDED Requirements
+
+### Requirement: User can switch between light and dark themes
+The system SHALL allow the user to toggle between light and dark themes with a persistent preference.
+
+#### Scenario: User toggles dark mode on
+- **WHEN** the user activates the theme toggle while the app is in light mode
+- **THEN** the system applies the dark theme and saves the preference for future visits
+
+#### Scenario: User toggles dark mode off
+- **WHEN** the user activates the theme toggle while the app is in dark mode
+- **THEN** the system applies the light theme and saves the preference for future visits
+
+### Requirement: Theme preference respects system defaults on first visit
+The system SHALL use the user's system color scheme preference when no saved preference exists.
+
+#### Scenario: No stored preference uses system theme
+- **WHEN** the user opens the app for the first time without a saved theme preference
+- **THEN** the system applies dark mode when the operating system prefers dark color schemes and light mode otherwise
+
+### Requirement: Theme selection loads without a flash of the wrong theme
+The system SHALL initialize the theme before the first visible paint so the page does not briefly render in the wrong theme.
+
+#### Scenario: Initial paint matches saved theme
+- **WHEN** the app loads and a saved theme preference exists
+- **THEN** the document theme is applied before the page content is visibly rendered
