Sift Portal Mechanics: Breaking a Note Block should collapse the portal

With The Sift dimension on the horizon, we know music and note blocks will likely play a massive role in opening the portal. To make this mechanic feel distinct from Nether and End portals, the portal should require a continuous "harmonic anchor." The Feature: If a player opens the Sift portal using the note block sequence, the portal should remain unstable. If a player breaks, shifts, or alters even one of the active note blocks, the beacons that are coming out of the note blocks disappear and the portal collapses. I also want to say that the beacons stay even when the process is done Why this fits Minecraft: 1. High Stakes: It prevents players from simply activating the portal once, stealing the note blocks, and leaving. 2. Grief Prevention/Traps: It introduces amazing Redstone traps and puzzle elements for custom maps or multiplayer servers. 3. Deep Dark Lore: The Deep Dark is all about sound, frequency, and vibration. If you disrupt the sound frequency holding the rift open, the connection to the Sift should naturally sever. Same also happens if you break a part of the frame. Portal blocks also give off a blue light in vibrant visuals and when the portal is disintegrating you can go in the portal blocks that are remaining before it fully disintegrates (portal also shuts in sift side)
