migrate to Next.js + TypeScript + React

[undeemed]

Summary

Full migration from static HTML/CSS/JS to Next.js 15 App Router + TypeScript + React 19. Same four pages, same visuals, same GSAP animations — now type-safe, statically prerendered, with proper component reuse.

What's in this PR

App Router routes (all server components, prerendered to static HTML at build time):

• app/page.tsx — / 42nights agency landing
• app/recon/page.tsx — /recon platform page (with the perimeter SVG diagram + glass overlay)
• app/pulse/page.tsx — /pulse GTM cockpit (lime theme)
• app/helm/page.tsx — /helm portfolio cockpit (blue theme)

Shared components:

• components/Nav.tsx — handles all four pages with the right links and brand mark per page
• components/Footer.tsx — studio vs product variants
• components/Marquee.tsx — flat span sequence so flex gap works
• components/Terminal.tsx — generic; takes a lines prop array of { prompt, cmd | out, outClass? }
• components/RadarMark.tsx — the radar SVG icon

GSAP:

• components/GsapClient.tsx — 'use client'. The full main.js logic, ported to a single useEffect keyed to pathname. On route change, all ScrollTriggers are killed and re-initialized; pointermove listeners on the spotlight are removed; the marquee tween is killed.
• gsap installed as an npm dep (was a CDN script before)

Theming:

• body[data-theme="helm"] → [data-theme="helm"] in CSS so any wrapper element can act as the theme root
• Each page wraps content in <div data-theme="agency|recon|helm"> — CSS variables cascade through descendants
• rm-progress and a couple other accent gradients changed from hardcoded lime to --accent/--accent-glow so they auto-theme

Removed:

• index.html, recon.html, pulse.html, helm.html, main.js, styles.css, vercel.json — all replaced by the Next.js project

Build

```
✓ Compiled successfully in 1.6s
✓ Generating static pages (7/7)
Route Size First Load JS
○ / 2.7 kB 153 kB
○ /helm 2.7 kB 153 kB
○ /pulse 2.7 kB 153 kB
○ /recon 2.7 kB 153 kB
```
All four pages prerender as static. Total shared JS 102 kB (mostly GSAP + Next/React runtime).

Test plan

• CI / Vercel deploy preview builds clean
• All four routes render identically to the static deploy
• Navigation between routes uses next/link soft nav and re-runs GSAP cleanly
• Hero title words slide-in animates on each page
• Roadmap timeline phase dots still toggle and the progress fill animates
• Roadmap product tabs (on /recon) swap panels
• Terminal typewriters fire when scrolled into view
• Theme colors are correct: denim on /, lime on /recon and /pulse, blue on /helm
• Mobile breakpoints look right
• reduced-motion users get static layout
