Summary

Added a dark-mode toggle using CSS custom properties and prefers-color-scheme. The toggle writes to localStorage so the choice persists across navigations.

Conversation

Turn 1 — User

Add a dark mode toggle. Should respect system preference by default but override on click.

Turn 1 — Assistant

Using data-theme on <html> and swapping CSS custom properties. The toggle button writes localStorage.setItem('theme', next), and a tiny inline script in <head> reads it before first paint to avoid a flash.

Tools used in this turn: - Edit: public/style.css — added [data-theme="dark"] vars - Write: templates/theme-init.html (5-line preview) - Edit: templates/base.html — included the init snippet
