/** * File: public/css/style.css * Purpose: Main stylesheet for the Notak3 application. * Defines CSS custom properties (design tokens) for light and dark themes, * base resets, the app-shell layout (sidebar + main content), header, * glass-panel cards, buttons, the dual-pane editor, AI score meter, * copy-gate overlay, auth pages, and the premium footer. * Theme switching is achieved by setting [data-theme="dark"] on . * * Future Improvements: * - Add CSS custom property for accent colour so the user's chosen colour applies globally. * - Extract component styles into separate files and bundle with a build step. * - Add @layer declarations to improve specificity management. * - Add print media query so the /editor page prints cleanly. * - Animate sidebar collapse with overflow:hidden + max-width for smoother transition. */ :root { /* Colors - Light Theme */ --bg-main: #F8F7F4;
