Add effect T-05 Scroll-Scrubbed Text to (SELECTOR)

Use SplitText.create() to split the element by words.
Set all words to opacity: 0.15 initially using gsap.set().

Animate each word's opacity from 0.15 to 1 using:
- stagger: { each: 0.15, from: "start" }
- ease: "none"
- ScrollTrigger:
  - scrub: 1
  - start: "top 75%"
  - end: "bottom 60%"

Words above the active scroll zone should remain at full opacity.
Words below should remain ghosted.
No snap, no toggle, no trigger — pure scrub only.

Note:
Opacity is used intentionally (partial values 0.15 to 1).
Do not use autoAlpha — elements must remain in flow and visible at all times.

Register SplitText and ScrollTrigger.
Load GSAP from CDN if not already present.
Wrap everything inside DOMContentLoaded.
