/* * FileLens — landing site stylesheet. * * One file for two pages: the landing page and the privacy policy. They share a * header, a footer and a token set, so splitting them would mean keeping two * copies of the same header in step by hand. * * The palette is the extension's own, not a second one invented for the web. The * accent is `--accent` from `src/ui/tokens.css` (#0b6e4f light, #43be93 dark), and * the deep slate the icon's tile is drawn on (#0e1f31 → #123246) carries the dark * theme's surfaces. The store icon, the app and the site are one palette rather * than three, and a change to the app's accent is a change here. * * Theme: `data-fl-theme` on is the resolved theme ('light' or 'dark'). * `data-fl-theme-choice` records what the user picked, which may be 'auto'. * script.js owns both; nothing here reads prefers-color-scheme directly, so the * toggle wins in every direction. */ :root { --fl-surface: #ffffff; --fl-sunken: #f4f7f5; --fl-text: #2a3138; --fl-heading: #10181f; --fl-muted: #556069; --fl-faint: #6b7680; --fl-border: rgba(16, 24, 31, 0.12); --fl-border-strong: rgba(16, 24, 31, 0.2); --fl-accent: #0b6e4f; --fl-accent-hover: #095c42; --fl-accent-ink: #ffffff; --fl-accent-soft: #e4f1eb; --fl-accent-line: #0b6e4f; --fl-amber: #8a5a00; --fl-json-key: #0b6e4f; --fl-json-string: #9a4a00; --fl-json-number: #1d4ed8; --fl-json-bool: #7c3aed; --fl-shadow: 0 24px 70px rgba(12, 32, 26, 0.13); --fl-shadow-soft: 0 14px 36px rgba(12, 32, 26, 0.08); --fl-radius: 16px; --fl-radius-sm: 10px; --fl-container: 1140px; --fl-mono: ui-monospace, SFMono-Regular, 'SF Mono', Menlo, Consolas, 'Liberation Mono', monospace; } * { box-sizing: border-box; } html { scroll-behavior: smooth; } @media (prefers-reduced-motion: reduce) { html { scroll-behavior: auto; } *, *::before, *::after { animation-duration: 0.01ms !important; transition-duration: 0.01ms !important; } } .fl-page { margin: 0; min-width: 320px; overflow-x: hidden; background: radial-gradient(circle at 12% 2%, rgba(11, 110, 79, 0.09), transparent 26rem), radial-gradient(circle at 84% 5%, rgba(18, 50, 70, 0.07), transparent 24rem), linear-gradient(180deg, #fbfcfb 0%, #ffffff 36%, #fbfcfb 100%); color: var(--fl-text); font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', system-ui, 'Helvetica Neue', sans-serif; line-height: 1.55; text-rendering: optimizeLegibility; -webkit-font-smoothing: antialiased; } .fl-page[data-fl-theme='dark'] { --fl-surface: #14232b; --fl-sunken: #0b161c; --fl-text: #d5dee2; --fl-heading: #f1f6f4; --fl-muted: #9aa8ae; --fl-faint: #859399; --fl-border: rgba(154, 168, 174, 0.2); --fl-border-strong: rgba(154, 168, 174, 0.32); --fl-accent: #43be93; --fl-accent-hover: #5bd0a6; --fl-accent-ink: #06221a; --fl-accent-soft: #102a22; --fl-accent-line: #43be93; --fl-amber: #e0a94f; --fl-json-key: #43be93; --fl-json-string: #e0a15a; --fl-json-number: #7fa9f5; --fl-json-bool: #b79bf0; --fl-shadow: 0 24px 70px rgba(0, 0, 0, 0.5); --fl-shadow-soft: 0 14px 36px rgba(0, 0, 0, 0.34); background: radial-gradient(circle at 12% 2%, rgba(67, 190, 147, 0.14), transparent 26rem), radial-gradient(circle at 84% 5%, rgba(18, 50, 70, 0.5), transparent 24rem), linear-gradient(180deg, #0e1a20 0%, #11202a 42%, #0e1a20 100%); } /* :where() so this reset carries ZERO specificity.
