/* ============================================================================ SafeZone AI · Learning platform stylesheet. ONE token system, TWO themes, ONE type scale. Rules of the file: - Every color is a token from the :root block (or a color-mix of one). No stray hex values in component rules — that is how the old sheet ended up with two palettes. - Every font-size is a --fs-* step. No fractional px sizes. - Dark is the product's native theme (bare :root). Light is applied by the OS preference, and an explicit user choice (data-theme on , set by theme.js) beats the OS in both directions. - Canvas renderers read these same tokens via RLTheme (theme.js), so the maze, race cards and training curves follow the theme too. ========================================================================== */ :root { /* -- surfaces & text (dark: the native theme) -- */ --bg: #0f1117;
