/*
 * pomodoro -- tool-specific styles.
 *
 * The dial, the session tabs, the controls and the ambient mixer. Colours are
 * the tokens from src/tailwind/input.css, so the dark theme needs few twin
 * rules. One accent: a focus session draws its ring in the accent, a break in
 * a lighter tone of it. Shared documentation styles live in
 * src/stemkit-docs.css.
