- Around line 70-71: Update the initial theme-selection logic and the
theme-toggle handler to synchronize the theme-color meta element with the
selected theme, using the active html.dark state rather than only
prefers-color-scheme media queries. Ensure the browser toolbar color is set
correctly on initial load and after every toggle, and remove or replace the
conflicting static theme-color declarations.
- Line 262: Update the dark-theme toggle around the aria-label to expose its
current state: synchronize aria-pressed with html.dark and update the action
label when initialization or toggle logic changes the theme. Keep the existing
aria-label wording structure while ensuring persisted dark-theme state is
reflected on initial load and after toggling.

Synchronize theme-color with the selected theme.
These media queries use only the operating-system preference. A stored explicit theme changes html.dark, but it cannot change the matching media query. For example, a user who selects dark mode on a light-mode system gets dark page content with a white browser toolbar. Update one theme-color meta element during initial theme selection and after each toggle.

Expose the active theme state to assistive technology.
aria-label stays unchanged and the button has no state attribute. A screen reader user cannot determine whether the persisted dark theme is active. Synchronize aria-pressed and the action label when initialization and toggle code change html.dark.

Sync theme-color meta with explicit theme choice instead of OS-only media queries. Expose toggle state via aria-pressed and action label.

Add dark text to DMCA page for consistency. Set color-scheme: dark so scrollbars and native controls follow the theme.
