| name | dreamcore-landing |
| description | Use this plugin when the user wants a single-page immersive parallax landing page with a scroll-driven portal/curtain entrance and a curved arc card slider — a 'dreamcore' / 'reverie' hero that scales a portal image toward the viewer as the user scrolls into a second dream-world scene. Invoke for 'parallax landing', 'scroll cinematic hero', 'portal zoom landing', 'arc card slider', or when the user references the Dreamcore Landing template. |

Dreamcore Landing — Immersive Parallax Scroll Hero
Produce a single-page immersive parallax landing page with two scroll-driven scenes inside one sticky viewport. A complete, rendered reference implementation ships beside this skill at example.html — start from it. Copy example.html, then adjust copy and data; do not rewrite the layer math, the easing, or the visual language. The seed already encodes the exact layer stack, scroll mapping, entrance sequence, mouse parallax, and arc-slider geometry described below.
This is the authoritative build brief. Follow it exactly — the layer z-order, scale ranges, scroll breakpoints, MAG values, fonts, image URLs, and card data are locked.
Stack
- Default output: a single self-contained HTML file (the
example.html seed). Vanilla HTML/CSS/JS, no build step. Framework features are mapped down: useScroll/useTransform → a passive scroll listener writing scrollProgress; per-frame transforms → a requestAnimationFrame loop; mouse parallax → a mousemove handler lerped at speed = 0.07; entrance animation → setTimeout milestones.
- If the user explicitly asks for the React + TypeScript + Tailwind + Vite project, port the seed faithfully into a single
src/App.tsx: same layer stack, same easing helpers (easeInOut, lerp, clamp), same MAG values, lucide-react as a (largely unused) dependency, Tailwind only for the responsive breakpoints. Override the xl breakpoint to 1100px (screens: { xl: '1100px' }). Do not change the design while porting.
Fonts & Global

Architecture
- Outer container:
height: 480vh; position: relative. Inside it: a position: sticky; top: 0; height: 100vh; overflow: hidden; background: #0a0608 viewport. All layers stack via absolute positioning + z-index.
scrollProgress = clamp(window.scrollY / (container.scrollHeight - window.innerHeight), 0, 1).- Helpers:
easeInOut(t) = t<0.5 ? 2*t*t : -1+(4-2*t)*t; lerp(a,b,t); clamp(v,mn,mx). isMobile() = matchMedia('(max-width: 767px)').
ep = easeInOut(scrollProgress) drives every layer's scale.
Layer Stack (bottom → top by z-index)
- World Background (z 0):
WORLD_BG, inset 0, object-fit: cover, transform-origin: 50% 50%. Scale lerp(1, 1.18, ep). Mouse MAG = 6.
- Bottom Clouds (z 10):
BOTTOM_CLOUDS, bottom 0, width:100% height:auto, transform-origin: 50% 100%. Scale lerp(1, 1.4, ep). Mouse MAG = 9 (Y dampened ×0.4). Opacity fades 0.7→1 in first 5% of scroll.
- Arc Card Slider (z 9): absolute,
bottom: 60px (mobile)/80px (desktop), centered. Opacity = scene2Opacity. Holds <ArcCardSlider> (geometry below).
- Portal Frame (z 15):
PORTAL_BG, inset 0, object-fit: cover, transform-origin: 52% 38%. Scale lerp(1, 7.5, ep) — the zoom-into-portal. Mouse MAG = 7. Opacity 1 until scroll 0.65, fades to 0 by 0.85.
- Bottom Fade (z 16): bottom,
height: 40%, linear-gradient(to top, rgba(0,0,0,0.45) 0%, transparent 100%), pointer-events: none.
- Curtain Left (z 16):
CURTAIN_LEFT, inset 0, object-fit: cover, object-position: right center, transform-origin: left center. Entrance: after 100ms shift translateX(-62%) with transition: transform 1.8s cubic-bezier(0.16, 1, 0.3, 1). On scroll: additional translateX -lerp(0,150,ep)%, scale lerp(1,1.3,ep). Mouse MAG = 14 (Y ×0.3). After 2200ms, transition → none for instant parallax.
- Curtain Right (z 16): mirror —
transform-origin: right center, object-position: left center, shifts +62% then +lerp(0,150,ep)%, MAG = 14.
- Top Fade (z 45): top,
height: 42vh, linear-gradient(to bottom, rgba(0,0,0,0.45) 0%, transparent 100%), pointer-events: none.
Navigation (z 50)

Scene 1 UI (z 20)
Opacity = clamp(1 - scrollProgress/0.22, 0, 1). Three Tailwind-responsive layout blocks (no JS layout branching):
- Mobile (
md:hidden, padding 80px 24px 100px, centered column): heading "FALL › INTO" (clamp(26px,7vw,42px), tracking-widest, #3b1a0a) then "REVERIE" (clamp(52px,16vw,80px), tracking-tight, leading-none, #3b1a0a). The › is #6b2e0e at 0.8em; "INTO" is italic. Subtext 15px, #5c2d0e, max-width 280. One 140×140 reel card.
- Tablet (
hidden md:flex xl:hidden, gap 28): same heading dark-brown (sizes clamp(28px,5vw,44px)/clamp(60px,12vw,86px)), subtext 16px max-width 400. Three 140×140 cards (gap 14): card1 reel, card2 number "32" + "World Patrons", card3 reel.

Cards block absolute right:40px top:50% translateY(-50%) gap 12, three 158×158 cards radius 28 box-shadow: 0 8px 32px rgba(0,0,0,0.45).
Reel card anatomy (all sizes): border-radius 22px (mobile/tablet) / 28px (desktop), CARD_IMAGES[i] background-cover, gradient overlay (60% height), backdrop-blur layer (44% height, masked gradient), bottom content at 12px inset. Play cards = white circle (26/30px) + play-triangle SVG + "View Reel" (13/18px). Number card = "32" Viaoda Libre (28/36px) + "World Patrons".
- Slider dots (bottom):
28px (mobile centered) / 40px (desktop left:60px). 4 dots, first 28px wide active, rest 14px, all 4px tall radius 2. Active rgba(255,255,255,0.9), inactive rgba(255,255,255,0.35).

Scene 2 UI (z 46)
Opacity = clamp((scrollProgress - 0.68)/0.16, 0, 1). Centered column, margin-top 8vh (mobile)/12vh (desktop).
- Heading (Viaoda Libre): "FORGE BEYOND THE REAL" —
clamp(28px,8vw,44px) mobile / clamp(38px,6.5vw,78px) desktop, white, ls 0.03em, line-height 1.05, text-shadow: 0 2px 20px rgba(0,0,0,0.4).

14px/20px, line-height 1.6, ls -0.01em, max-width 260/480, rgba(255,255,255,0.82).
Arc Card Slider Component
9 cards (data below). Props: cards[], rotationOffset, isMobile.
Layout math — cardSpacingDeg: 12 (mob)/9 (desk); centerIndex = floor(9/2) = 4; arcRadius: 700/1100; cardW: 160/220; cardH: 175/230; sliderH: 260/360. arcSweepDeg = (9-1)*10 = 80. rotationOffset = lerp(0, arcSweepDeg, clamp((scrollProgress - 0.70)/0.30, 0, 1)).
Per card: baseDeg = (i - centerIndex)*cardSpacingDeg; deg = baseDeg - rotationOffset + (centerIndex*cardSpacingDeg); rad = deg*PI/180; x = sin(rad)*arcRadius; y = arcRadius - cos(rad)*arcRadius. Position absolutely at bottom: -y + (140 mob/200 desk)px, left: calc(50% + x - halfW), transform: rotate(deg), transformOrigin: halfW arcRadius.
Appearance: rounded rect (18px/26px), background = card.color (pastel), box-shadow: 0 8px 40px rgba(80,40,60,0.18). Top-right numbered circle (24px, 1.5px border rgba(80,50,60,0.3), text rgba(80,50,60,0.6), 10px Imprima, zero-padded index). Bottom: title Viaoda Libre (22px/30px, #3a2530) + desc Imprima (12px/15px, rgba(58,37,48,0.65)).

Entrance Sequence
- t=100ms:
curtainsOpen → true → 62% horizontal shift on each curtain with 1.8s cubic-bezier(0.16, 1, 0.3, 1).
- t=600ms:
uiVisible → true → Scene 1 UI fades/slides in (opacity 0.9s ease, transform 0.9s ease) with staggered delays: heading 0.3s, cards 0.55s, dots 0.8s, scroll cue 0.9s.
- t=2200ms:
entranceDone → true → curtain transition switches to none so parallax is instant.
Mouse Parallax (desktop)
requestAnimationFrame loop lerps raw mouse position at speed = 0.07. Each layer offsets by its MAG in the reverse direction of the mouse, combined with the scroll-driven scale/translate. MAG: world=6, clouds=9, portal=7, curtainL=14, curtainR=14.
Hard Rules
- The portal scale range
lerp(1, 7.5, ep) and curtain entrance -62%/+62% are the signature motion — do not reduce them.
- Keep all five Cloudinary stills and the three higgs.ai card images as remote URLs; they are large stable CDN media. Do not inline them, do not swap the host.
- No external avatar hosts (
i.pravatar.cc, api.dicebear.com) — this template uses no avatars.
- Fonts are locked: Viaoda Libre (serif headings) + Imprima (body). Background
#0a0608.
- Scroll breakpoints are locked: scene1 fades by 0.22; portal fades 0.65→0.85; scene2 fades in 0.68→0.84; arc rotation drives 0.70→1.0.
