Dark mode and font size

Switching theme

• The ☀️ / 🌙 / 🖥️ button in the top nav cycles through light → dark → follow system.
• On the home page before you sign in, the moon / sun button at the top switches between light and dark; to go back to "follow system", use the button in the navigation bar on other pages or your account page.
• You can also choose it in the "Appearance" section of the Account page, and adjust the font size (small / medium / large).

Notes

• "Follow system" switches automatically based on your OS / browser dark-mode setting.
• Preferences are stored in your browser (locally); switching devices needs a reset, and clearing browser data reverts to defaults.
• Font-size adjustment scales all interface text proportionally for easier reading.
