feat(skills): c2v mining pass — 7 new blueprints, 10 new rules, compacted recipe corpus (#2680)

* feat(skills): c2v mining pass over animation blueprints and rules

Compacts ~45 existing animation rules/blueprints into tighter recipe form
(net -3.4k lines) and adds 17 mined from the c2v corpus:

- 7 blueprints: agent-progress-theater, camera-journey, fixed-anchor-cycle,
  panel-edit-live-sync, prompt-type-submit-generate,
  transcript-scroll-artifact-reveal, zoom-out-workspace-reveal
- 10 rules: 3d-camera-flight, anchored-layout-expand, chart-scrub-readout,
  chromatic-glitch, control-target-sync, cursor-drag, gradient-text-sweep,
  multi-cursor-choreography, particle-burst, theme-crossfade-morph






Both indexes updated.

* feat(skills): sync product-launch script bank with mined blueprint roles

The role->blueprint script bank in product-launch-video/story-design.md is
kept 1:1 with blueprints-index role declarations, which the c2v mining pass
expanded. Adds the 25 missing entries (script-shape descriptor + example
lines + pattern): 13 for the 7 new blueprints, 12 for role widenings on 7
existing ones (cursor-ui-demo, dataviz-countup, titlecard-reveal, et al.),
and states the 1:1 sync contract in the bank's intro.

* docs(skills): cover constellation-hub scatter-drift variant in the script bank

Review follow-up on #2680: the SOCIAL_PROOF constellation-hub entry
patterned only the orbit shape; the c2v pass added a scatter-drift
end-card variant with the opposite geometry (no hub, no ring). Adds an
example line and extends the pattern so a scatter-drift beat's VO isn't
steered toward the orbit shape.

 **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: all three drafts are Key_Feature; this blueprint is role-narrow but mechanic-rich — variants differ by MECHANIC, not role.)
+- 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.

 **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.

 - 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.
