Spiderman UI

	SpiderWebSwing (LocalScript)

	PLACEMENT: StarterPlayer > StarterPlayerScripts
	(It needs to live here because it has its own persistent UI/settings that
	 should survive dying and respawning. The character is re-acquired
	 automatically every time you respawn.)

	FEATURES:
	  - Only ONE web at a time: shooting a new one instantly removes the old one.
	  - The string visually shoots out from your hand to the target over a
	    fraction of a second (speed scales with distance, WEB_TRAVEL_SPEED)
	    instead of just appearing at full length. The real physics rope only
	    attaches once it "lands".
	  - Speed boost: your current speed is amplified when you shoot a web while
	    already moving, and holding WASD while swinging accelerates you further
	    (up to a cap, MAX_SWING_SPEED).
	  - Real swing feel: while a web is attached, the Humanoid is put into
	    "Physics" state so Roblox's normal walking control never takes over and
	    zeroes your speed when you're near the ground at the bottom of the arc.
	  - Release with high speed (see SLIDE_MIN_SPEED) and you fly off, then
	    gradually slow down (SLIDE_FRICTION) instead of stopping dead.
	  - Loose/"ragdoll" feel WITHOUT looking ragdolled: the web attaches
	    slightly above your center of mass (SWING_HAND_HEIGHT), which gives a
	    natural lean during swings instead of perfectly rigid motion, and
	    AutoRotate is turned off so you're not forced to face your direction
	    of travel. A weak AlignOrientation (ORIENTATION_MAX_TORQUE /
	    ORIENTATION_RESPONSIVENESS) only stops you from ending up permanently
	    upside-down - your body always looks completely normal (no loose
	    limbs, no broken joints). This loose feel starts the moment you shoot
	    a web and lasts through the whole time you're airborne - including
	    after you release it - and only ends the instant you actually touch
	    the ground. While a web is still attached it NEVER ends early (even
	    if you brush the ground mid-swing), so the pendulum can't get "stuck"
	    at the bottom of a low arc.
	  - A small settings UI that's open by default. Drag the header
	    ("SPIDER WEB") to move the panel, click "–" to collapse it to just the
	    header, or click "X" to fully close it (this also automatically turns
	    the whole mechanic OFF). Click the spider tab on the left edge to
	    reopen it. In the panel you can:
