name	mythic-naturecore
description	Use this plugin when the user wants a cinematic mythic-naturecore landing page — the 'Reverie' template: a scroll-linked zoom-through-a-portal hero with mirrored opening curtains, a layered world background, mouse-parallax 3D depth, and an elegant Viaoda-Libre/Imprima serif+sans pairing. Invoke for 'naturecore landing', 'portal scroll page', 'Reverie', 'cinematic parallax hero', or when the user references the Mythic Naturecore template.

Mythic Naturecore — "Reverie" Cinematic Parallax Landing

Produce a high-fidelity, premium interactive landing page named "Reverie". A complete, rendered reference implementation ships beside this skill at example.html — start from it. Copy example.html, then adjust copy and imagery only; do not rewrite the scroll/parallax math or invent a new visual language. The seed already encodes the exact fonts, asset map, scroll timeline, parallax magnitudes, and entrance sequence below.

The native spec asks for React + TypeScript + Tailwind + inline styles; the bundled seed is vanilla HTML/CSS/JS with the framework features mapped down (no useScroll/useTransform/Framer — a passive scroll listener writes scrollProgress, a requestAnimationFrame loop writes inline transform, a mousemove handler drives the magnetic parallax). When the user explicitly asks for a React/Vite project, port the seed faithfully: same tokens, same layer structure, same math.

This is the authoritative build brief. The named curve constants, magnitudes, scroll heights, and asset URLs are locked.

Stack & fonts

• Default output: the single self-contained example.html seed.
• Fonts via Google Fonts <link>:
  • Headings: 'Viaoda Libre', serif.
  • Body, nav links, captions: 'Imprima', sans-serif (also the body default).

Global reset

html, body { margin: 0; padding: 0; background: #0a0608; scroll-behavior: auto; }
html { scrollbar-gutter: stable; }       /* prevent layout shift */
body { font-family: 'Imprima', sans-serif; }
@keyframes bobUp { 0%, 100% { transform: translateY(0); } 50% { transform: translateY(-6px); } }

Asset map — LOCKED (large stable CDN stills, kept REMOTE)

Define these exact constants at the top of the script. These are big background stills on a stable CDN (res.cloudinary.com); per the inline-vs-remote rule they stay remote — do NOT re-host, swap the host, or inline them.

Math helpers — LOCKED

easeInOut(t) = t < 0.5 ? 2*t*t : -1 + (4 - 2*t)*t
lerp(a,b,t)  = a + (b - a) * t
clamp(v,min,max) = Math.max(min, Math.min(max, v))

Scroll + mouse system

• Page height is exactly 480vh (#scroll-root); inside it a single sticky #stage spans 100vh (position: sticky; top: 0; overflow: hidden).
• scrollProgress ∈ [0,1] = clamp(scrollY / (scrollRootHeight - innerHeight), 0, 1), written by a passive scroll listener.
• useIsMobile() ⇒ a matchMedia('(max-width: 767px)') flag.
• Mouse parallax: normalize rx, ry ∈ [-1,1] from cursor vs viewport center. A requestAnimationFrame tick() lerps current→target with step 0.07 every frame (kills frame-rate stutter), then writes inline transforms.

Animation timeline (applied every frame)

• World (WORLD_BG): scale lerp 1 → 1.18; transform = scale(s) translate3d(rx*6px, ry*6px, 0).
• Portal (PORTAL_BG, transform-origin: 52% 38%, above world): scale lerp 1 → 7.5 (immersive zoom-through); opacity = clamp(1 - (p - 0.65)/0.2, 0, 1); transform = scale(s) translate3d(rx*7px, ry*7px, 0).
• Curtain Left (CURTAIN_LEFT): opening offset 62% left, scrolls further to 150% via eased: totalShift = 62 + easeInOut(p)*88. Scroll scale lerp 1 → 1.3. transform = translateX(calc(-totalShift% + rx*14px)) translateY(ry*14*0.3px) scale(scrollScale) translateZ(0).
• Curtain Right (CURTAIN_RIGHT): symmetric mirror — same but translateX(calc(+totalShift% + rx*14px)).

Entrance sequence

Curtains start fully closed (translateX(0)); after 100ms they open to the 62% resting offset; UI fades in after 600ms (opacity + 20px slide-up, 0.9s ease, hero delayed ~300ms). After 2200ms disable the entry CSS transitions so mouse parallax has zero lag.

Color rules — hard

Cinematic naturecore palette: near-black base #0a0608, warm dark-brown mobile text #3b1a0a, white desktop text, translucent white captions. Keep the serif/sans pairing (Viaoda Libre + Imprima). Do not introduce neon, purple, or flat material accents — the mood is dim, organic, painterly.

Responsive

• ≥1100px desktop split-screen white-text hero; 768–1099px tablet centered 3-card row; <768px mobile centered single-card dark-brown hero, mobile nav, dots centered, scroll cue hidden.
