update how it works

Migrate the standalone Vite + React Three Fiber experience into the existing
Next.js site as the body of the How It Works page, replacing the Miles3 /
WhyChooseDoormile / TheDoormileWay content sections while preserving the
Elementor hero, global Header/Footer, layout, routing and SEO.

- New self-contained module: src/modules/how-it-works-3d/ (R3F scene, hooks,
  zustand store, animations, curves, constants, utils, scoped CSS). App.jsx →
  Experience3D.jsx; 3d_scene.jsx → models/Scene3D.jsx.
- 32MB GLB moved to public/models/3d_scene_final.glb; useGLTF paths updated.
- Client-only entry via dynamic ssr:false loader (Experience3DLoader).
- Self-managed fixed pin (tall section + absolute stage toggled
  absolute(top)→fixed→absolute(bottom) from ScrollTrigger pin state), mirroring
  the site's StrategySection, since the fixed header + ancestor overflow:hidden
  break CSS sticky / GSAP pin.
- experience.css fully scoped under .dm-hiw-3d to avoid colliding with the
  site's Elementor CSS.
- Global Lenis disabled on /how-it-works; module runs its own tuned Lenis;
  jump-to-section scroll math made spacer-relative.
- Added zustand + maath; ESLint-ignored the ported module.

Rendering fixes (root causes found by driving headless Chrome):
- Bump three 0.171 → 0.184 to match @react-three/fiber@9.6 / drei@10.7 /
  postprocessing@6.39 (0.171 silently failed to render this GLB and caused the
  EffectComposer getContextAttributes().alpha crash). Other 3D routes verified.
- EffectComposer: Bloom + Vignette only. SSAO needs a NormalPass (v3 dropped
  the old `disableNormalPass`), and that extra full-scene pass exhausted the
  WebGL context on this heavy scene.
- Cap Canvas dpr to [1,1.5] to bound framebuffer memory on retina displays.
- Defer Canvas mount via IntersectionObserver (mountScene), matching
  StrategySection, to ease StrictMode/first-render GPU pressure.

+ * Experience3D
+ * ---------------------------------------------------------------------------
+ * The full scroll-driven 3D logistics story, ported from the standalone Vite
+ * app's App.jsx and embedded as the body of the How It Works page (below the
+ * existing Elementor hero, above the global Footer).
+ *
+ * Two integration changes vs. the standalone app:
+ *  1. Self-managed fixed pin. The site has a fixed header and an ancestor with
+ *     `overflow:hidden`, both of which break CSS `position: sticky`. So this is
+ *     a tall `position:relative` section (`.dm-hiw-3d`, its height supplied by
+ *     the 900vh ScrollRig spacer) with an absolutely-positioned `.dm-hiw-3d-stage`
+ *     toggled absolute(top) → fixed → absolute(bottom) via the ScrollTrigger pin
+ *     state — the same approach the site's other 3D sections use (StrategySection).
+ *  2. The global Lenis is disabled on `/how-it-works` (SmoothScroll.tsx) so the
+ *     experience runs its own tuned Lenis here without a second instance fighting
+ *     it. The internal "Scroll to start" Hero overlay is dropped because the page
+ *     keeps the Elementor HowItWorksHero above this section.

+   names (.navbar, .btn-primary, .section-title, .loader-overlay) that would

+
+   Pinning mirrors the site's existing scroll-driven 3D sections (see

+   positioned stage toggled absolute(top) → fixed → absolute(bottom) from
+   ScrollTrigger pin state. CSS `position: sticky` / GSAP pin are unreliable
+   here because the site has a fixed header and an ancestor `overflow:hidden`.
