   MindCare – Global Stylesheet
   ------------------------------------------------------------
   Purpose:
   - Defines all visual styling for the MindCare frontend
   - Paired closely with index.html + app.js
   - Dark mode handled via body.dark-mode class (JS controlled)

   ⚠️ IMPORTANT:
   - Many styles rely on JS-added classes (e.g. .active, .completed)
   - Do NOT remove selectors without checking app.js
   ============================================================ */

   1. CSS Reset & Global Design Tokens
   ------------------------------------------------------------
   - Reset default browser spacing
   - Define color palette and reusable variables
   - Variables are reused across all pages & dark mode
