   7. CSS "HOLE PUNCH" EFFECT
   -------------------------------------------------------------------------- */

/*
 * HOW IT WORKS:
 * 1. .section-with-hole has overflow: hidden and NO background of its own.
 * 2. .hole uses a massive box-shadow (9999px) in --color-bg to fill the
 *    entire section with a solid colour, but the element itself is transparent.
 * 3. This creates a "window" (the hole) that reveals the fixed parallax
 *    background behind it.
 * 4. All text outside the hole must use .text-on-top (z-index: 2) to sit
 *    above the shadow layer (z-index: 1).
 *
 * CONSTRAINT: Only one .hole per .section-with-hole. Multiple holes in the
 * same section will cause overlapping shadows that hide sibling content.
