/*
  Scroll connector — dashed line that draws itself between landing sections.
  Driven by scroll_connector_controller.js, which sets `--p` (0 → 1) and
  toggles `.is-lit` once the line reaches its node.

  Accent comes from `--connector-rgb` (a Catppuccin channel triplet such as
  var(--ctp-mauve-rgb)), so it follows Latte/Mocha automatically.
