1/* Fun Rádio — seamless navigation while a podcast is playing.
2   A normal page load tears down the <audio> element, which is audible as a gap.
3   While the mini-player has audio loaded we therefore swap only <main> via fetch +
4   History API, so the audio element (which lives on <body>) keeps playing untouched.
5   When nothing is playing we stay out of the way completely: full page loads, so the
6   GSAP entry animations behave exactly as designed. */
