Phase 3.3.5 Hotfix / 5

Modal hub + repaired compact deck.

This hotfix keeps the player compact, moves the Control Hub into an in-player modal, repairs the equalizer/player control fit, and starts turning the launcher into a wider visualizer and skin lab.

Browser reality: Chrome will still show its own title/address chrome. This build still uses an injected about:blank pop-out to conceal the ugly local file path. The player scales itself to fit tighter zoom/OS-scaling conditions so a 125% environment does not blow the deck apart.
Main-page skin lab: this launcher can now load a texture and push it into the open player. The pop-out keeps playback compact while this page can become the wider visualizer/skin workshop.
Ready.
