Device Surface Showcase

roles served

• Key_Feature (from key-feature-device-screen-tour, key-feature-floating-window-scroll, key-feature-3d-device-hand-demo): show a feature being _experienced inside its real interface* — the surface houses the action and its screens advance through a flow, rather than enumerating tiles or chasing a cursor across a workflow. (Note: the three founding drafts are Key_Feature and variants differ by MECHANIC, not role; the mined stepwise-flow variant widens the blueprint to Product_Intro.)
• Key_Feature (from demo-page-scroll-spotlight): the floating-window push-scroll variant carried to a spotlight climax — a real webpage rendered as a tilted 3D card coasts in (power2, like a phone held up — no spring), header keywords flare on a karaoke glow as the VO names them, the page rolls to the demoed section, and one element LIFTS off the surface (translateZ + scale) under a radial spotlight that dims the rest.
• Product_Intro (from stepwise-flow-completion): a compact end-to-end product flow — setup/auth → action → success/confirm — plays out cursorless as successive screen states inside the held surface, capped by a confirming button press; bookended by title-card beats. The surface introduces the product by _completing its core loop*, not by touring screens.
• Key_Feature (from showcase-carousel): the showcase-carousel — two surfaces in sequence (a widget card cycling brand skins, a phone frame with app screens sliding through it) gated by interstitial claim words; the screen cycle is a breadth carousel (“N brands / N apps”), not a flow.

duration: 5–11.3s (page-scroll-spotlight 5–9s · floating-window 7.8s · 3d-hand 7.9s · in-device approval 7.9s · stepwise-flow 8.5–9.4s · device-tour 9.6s · showcase-carousel 11.3s)

shot structure One product surface — a [device mockup] or a [floating browser/app window] — is the persistent hero on a [styled backdrop: gradient / radial / stylized 3D void]; its [screens/sections] cycle through a real [product flow] while a showcase camera (static-hold, push-in→zoom-out, or one continuous push) presents it. Each screen state holds ~1.0–1.5s.

• Scene 1 (0.0–~1.5s): The surface ESTABLISHES — it [slides in from an edge / drifts in from a tilt / dissolves from a full-frame title card] and settles, with a [accent shape or backdrop] resolving behind it; the first [screen] is visible. The showcase camera begins (see variants).

• Scene 2 (~1.5–~Xs): The surface is OPERATED on its own face — a [tap/select/scroll] triggers the first screen advance: old content [pushes out / scrolls up], new [screen/section] [pulls up / pushes in from the side]; concurrently a [label / header word / side headline] updates. The camera continues its move.

• Scene 3+ (~Xs–end, repeat for [2–4 screen beats]): The surface ADVANCES through successive [screens/sections], each a discrete swap or scroll synced to the surface’s flow, while the secondary copy [swaps out-up / in-up] or stays marked to hold reading position. HOLDS on the final [screen] (or, for one variant, blooms out — see variant).

• Variant — static-tour (key-feature-device-screen-tour, 9.6s): a [device mockup] slides in from off-screen and settles (ease-out); an [accent-color shape] scales up behind it (spring overshoot). Camera STAYS STATIC the entire clip — all motion is element/UI-level: a tap COMPRESSES a button (95%→100%), the UI scrolls/transitions to the next view (old pushes out, new pulls up), and a [side headline] SWAPS beside the device (old slides up + fades, new slides up + in) per screen. Holds on the final screen. No camera move, no cursor.

• Variant — floating-window (key-feature-floating-window-scroll, 7.8s): OPENS on a full-frame [title card] (a small [icon] draws in at center, [feature name] below; holds ~2s), which DISSOLVES to a [macOS-style browser/app window] floating on a [vivid gradient] (traffic-lights + [URL pill] + tabs; left nav, central content, right [sidebar]). Camera PUSHES IN on a [target region/sidebar] (active item highlighted [accent], a cursor drifts down the list), then ZOOMS BACK OUT to re-frame the whole window while the content SCROLLS through [sections]; the [highlighted item] stays marked. One push-in→zoom-out arc, gated by the title-card opener.

• Variant — 3d-hand (key-feature-3d-device-hand-demo, 7.9s): FULLY 3D — a [3D device] drifts in a [stylized 3D void / bloom + particles], opening tilted and self-rotating to face the lens nearly flat as ONE CONTINUOUS forward camera push begins (no cuts). A glossy [3D hand] rises from the bottom-foreground and GESTURE-DRIVES the surface: it swipes to scroll a [picker/sidebar panel] of [option cards] and taps [option] (while a [header word] letter-flips in place); the selection APPLIES — a [new layout] grows from center to fill the device face, nav flips, a [marquee] scrolls horizontally; the hand swipes again to scroll the page upward through [sections], then drifts out. The camera never stops pushing; the bright device face keeps growing toward the lens until it BLOOMS into a [light] wash — a zoom-through “portal” exit that fills the frame.

• Variant — stepwise-flow (Product_Intro, 8.5–9.4s; in-device Key_Feature sub-mode 7.9s): CURSORLESS end-to-end flow — the surface completes [setup/auth → action → success] as a narrative arc. Opens on a [title card] that fades in/out on an ambient gradient (or a typed [command] running character-by-character on a terminal field). The [flow surface] arrives (phone mock slides up oversized and settles / bordered log panel replaces the command) and step 1 completes via rapid sequential pops — [OTP digits] fill boxes left-to-right capped by a green check, or [log steps] pop top-down with highlighted tokens, ending on a trailing-dots waiting state. State advances laterally (old content slides out left, new in from right, chrome persists) or via a dark-to-light scene swap into a white [detail/confirm card] whose elements stagger in. COMMIT: the [CTA button] is pressed (press dip / spinner “Processing”) and a [success state] renders with check bullets — in the in-device sub-mode the commit runs a biometric ritual: dim overlay, [squircle] spring-pops, a ring draws around an icon, the icon morphs to a checkmark and holds; a slight camera push-in fires ONLY at the state transition (camera punctuates the commit, then re-locks). EXIT: the surface leaves and closing [title cards] pop in and ease smaller — the surface exits before the coda instead of holding. Camera otherwise static. For this variant the persistent hero is the FLOW, not one surface: a terminal panel may hand off wholesale to a confirm card.

• Variant — showcase-carousel (Key_Feature, 11.3s): TWO surfaces in sequence on a slowly drifting [pastel mesh gradient], static camera, gated by centered interstitial [claim words] (fade in with gentle scale-up, fade out). Act 1: a white [widget card] scales in, flips/morphs into a tilted vertical widget and CYCLES [N brand skins] (~0.8s each) — one shared layout, per-skin content and accent swaps — while a large [brand logo] crossfades below per flip; the widget scales away. Act 2: a [phone frame] enters oversized and tilted, settles upright at center; full [app screens] slide left through it (~1s each), holding on the last. The screen cycle is a breadth carousel, not a flow — no taps, no cursor, no camera.

rule mapping (per motion verb → backing rule, or flagged special)

• screen-cycling — UI scrolls/sections scroll inside the surface (device-tour, floating-window scroll, 3d-hand page scroll) → 3d-page-scroll (webpage/app as a tilted card whose content translateY-scrolls to sections; primary mechanic for the surface’s screen flow)
• floating-window establish + the surface presented as a tilted/floating UI card → 3d-page-scroll (the tilt/perspective framing) + css-3d-transforms (perspective/translateZ depth)
• screen / side-copy state swaps (discrete screen states; side headline content swapping per beat) → discrete-text-sequence
• side-headline reveal (staggered fade + slide-up) → discrete-text-sequence
• in-place header-word letter-flip (3d-hand) → hacker-flip-3d
• screen swap as a coordinated shrink-out / pop-in between two screen states → scale-swap-transition
• template-apply “new layout grows from center to fill the face” (3d-hand) → center-outward-expansion (clustered-at-center → expand to fill)
• the surface morphing between states / title-card→window dissolve as the eye-anchor transition → card-morph-anchor
• button tap-compress (95%→100% press feedback) → press-release-spring (or physics-press-reaction for a heavier press)
• floating-window cursor click on the highlighted list item → cursor-click-ripple
• accent-highlight pop on the active sidebar/list item → asr-keyword-glow (accent glow on the focused item)
• drifting cursor down the sidebar list (floating-window) → camera-cursor-tracking (flat-cursor drift; pairs with the push-in)
• floating browser-window idle float / 3D device drift-breathe → sine-wave-loop
• 3D device drift + self-rotate-to-camera + perspective depth (3d-hand) → css-3d-transforms (CSS-3D) or 3d.md technique (true Three.js/R3F device); see camera modifier
• horizontal [marquee] scroll (3d-hand) → viewport-change (PAN mode on the marquee strip) — thin fit; a literal CSS-marquee/translateX loop is closer to a gsap-effects/CSS recipe than a named motion rule
• 3D-hand entrance + swipe + tap as the interaction DRIVER (gesture input that scrolls/selects) → flagged special — needs a heavier capability beyond the rule library (R3F/Three.js + WebGL), NOT a motion-shape rule. The 3D hand model + WebGL bloom have a technique backing (3d.md — R3F, useGLTF HandModel, --gl=swiftshader for the shader/bloom), but no motion-shape rule models a 3D hand as the swipe-to-scroll / tap-to-select gesture protocol. context-sensitive-cursor / camera-cursor-tracking only model a flat typing/pointer cursor, not a 3D gesturing hand.
• zoom-through bloom / portal exit (3d-hand) → flagged special — needs a heavier capability beyond the rule library (WebGL), NOT a named transition rule. Capability is techniques.md → WebGL shader (via 3d.md headless WebGL: --gl=swiftshader --concurrency=1), but no named transition rule covers a bloom/portal fly-through.
• typed terminal command / non-linear log text (stepwise-flow) → discrete-text-sequence (typing + threshold state replacement) with dynamic-content-sequencing computing each step’s window from content length
• sequential top-down log pops / OTP digit pops left-to-right / staggered confirm-card build-in → spring-pop-entrance (staggered group form; low overshoot for log lines)
• trailing-dots wait state → sine-wave-loop (finite repeats; step the opacity of 3 dots on a shared phase)
• lateral screen slide with persistent chrome → the existing screen-cycling mapping (3d-page-scroll translateX form inside the clipped surface); chrome sits outside the sliding layer
• notification banner spring-in / squircle pop (in-device) → spring-pop-entrance
• lockscreen fade/blur-away + card expands to fill the device face → card-morph-anchor (uniform-scale container morph — never tween width/height) + depth-of-field-blur (the blur-away)
• commit-synced micro push-in (camera punctuates the Approve/tap, then re-locks) → multi-phase-camera (single short push phase placed at the state transition)
• button press dip + fill flip / Approve press-down spring-back → press-release-spring (already mapped; the fill flip is its color-transition variation)
• spinner processing state → svg-icon-enrichment (rotating internal element with explicit SVG center)
• success check bullets / biometric ring draw → svg-path-draw (check strokes; ring rotated −90° to start at 12 o’clock) + spring-pop-entrance for the bullet pops
• icon morph to checkmark (biometric ritual) → flagged special — SVG path morph, see hyperframes-keyframes (morph); no motion-shape rule models it — mechanics live in techniques.md / the keyframes skill, same tier as the blueprint's existing WebGL flags
• interstitial claim-word gate (fade + gentle scale-up, then out) → gsap-effects (plain fade/scale chord; deliberately quieter than kinetic-beat-slam)
• brand-skin cycling with per-flip logo crossfade → discrete-text-sequence (whole-state content replacement at thresholds) + scale-swap-transition where a flip reads as shrink-out/pop-in; the card→tilted-widget flip/morph → card-morph-anchor + css-3d-transforms
• drifting mesh-gradient backdrop → sine-wave-loop (very-low-amplitude position/hue drift on gradient blobs)

camera modifier: The showcase camera spans a RANGE keyed by variant, all on a single content-wrapping virtual camera (viewport-change):

• static-tour → NO camera move (viewport-change held at scale 1, or omitted); all motion is element-level. This is the floor of the range and what distinguishes the device-tour from the rest.
• floating-window → a two-phase push-in → zoom-out arc → multi-phase-camera (e.g. dramatic-reveal 1.1→1.0→0.95 feel): push IN on the [sidebar/region] via coordinate-target-zoom (off-center target = scale + counter-translate), then multi-phase-camera zooms back OUT to re-frame the whole window while content scrolls.
• 3d-hand → ONE continuous forward push (no cuts) → multi-phase-camera in steady-push mode (1.0→1.03→1.06… plus its sine micro-drift) layered over css-3d-transforms/3d.md so the device self-rotates-to-lens during the push; the push runs unbroken into the bloom/portal exit (exit itself is the WebGL-shader flagged special above). Across all three: viewport-change is the base virtual-camera primitive; multi-phase-camera sequences the push/zoom phases (and supplies the always-on micro-drift that keeps even the “static” tour from feeling dead); coordinate-target-zoom aims the push at off-center screen detail.

Overflow (pan/scroll surfaces — required for a clean check): a panned or scrolled surface deliberately moves content PAST the edges of its framing card. Clip it at the card (overflow: hidden on the card/window) AND mark the moving inner layer (the .world / surface wrapper holding the screenshot + any markers/labels) with data-layout-allow-overflow — otherwise check reports text_box_overflow / container_overflow errors for the parts that scroll off (e.g. a marker label panned off the left edge). The card clips them visually; the attribute tells the layout audit it’s intentional, not a layout bug.
