Neon Sign Text

Create a React + TypeScript component `NeonSign` that reproduces a photorealistic pink/violet neon sign mounted on a dark brick wall, with a wet-floor reflection — pure CSS/Framer Motion, no images required.

Build:
- Wall: a `div` with a subtle brick pattern made of `repeating-linear-gradient` layers over `#0b0409`, plus a vignette (`radial-gradient` mask) and a magenta ambient glow behind the text.
- Lettering: `font-black uppercase text-7xl md:text-9xl tracking-widest`, color `#fff0fb`, with outline-style neon via `WebkitTextStroke: '2px #f472b6'` combined with layered `textShadow` (`0 0 8px #f472b6, 0 0 24px #e879f9, 0 0 60px #c026d3, 0 0 120px #a21caf`).
- Ambient spill: an `aria-hidden` blurred copy (`blur-[60px] opacity-70`) tinted magenta, scaled 1.05.
- Reflection: duplicate with `scaleY(-1)`, `blur-[6px]`, `opacity-40`, horizontally distorted with `skewX(-4deg)` and masked to fade downward, plus a faint moving highlight to suggest wet concrete.
- Animation: idle hum `opacity: [1,0.94,1]` over 2.6s infinite; a random flicker on one letter — implement by mapping characters to `motion.span`s and giving a chosen index a keyframe burst every ~5s using a `repeatDelay`.
