   0. WEB FONTS

   @font-face lets you use custom fonts on your website.
   The browser will download and use this font instead of system fonts.

   IMPORTANT: Make sure the font file path is correct!
   ========================================================================== */

   1. CSS CUSTOM PROPERTIES (VARIABLES)

   CSS variables let you define values once and reuse them throughout.
   This makes it easy to change colors or fonts in one place!

   Usage: var(--variable-name)
   Example: color: var(--color-primary);
   ========================================================================== */

body {
    /* Remove default margin */
    margin: 0;
    /* Set the base font */
    font-family: var(--font-main);

    line-height: 1.5;
    /* Dark mode colors */
    background-color: var(--color-bg-page);
    color: var(--color-text-default);
    /* Improve text rendering on Mac/iOS */
