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**
 
 - CTA (from `cta-morph-press`): when the close moves from brand identity to a single user action, two elements share the same center sequentially (a morph, not a cut), and the payoff is a simulated click with physical feedback. Reach for it for a focused "click here" sign-off — no spatial set, no multi-step UI (that's `cursor-ui-demo`).
+- Hook (ROLE-WIDENED, from `widget-morph-on-blank-field`): the same
+  machinery run as an OPENER — a lone `[widget]` (pill / chip lockup) on a flat field transforms
+  in place, performs its payload, then vanishes to a plain frame that a typed `[title]` resolves.
+  The click, when present, ignites the morph rather than closing it; there may be no cursor at
+  all. Reach for it when the product hook IS one widget doing one thing — still no spatial set,
+  no multi-step UI (that's `cursor-ui-demo`). Mint-reconsideration trigger: if future mining
+  brings 2+ more widget-morph openers with the vanish → typed-title resolve, promote this variant
+  to its own blueprint (the beat order is fully inverted by then).

 - **Scene 2 (~1.4–2.4s) — the morph (signature move).** The hero CONDENSES at the same screen center into a smaller, brighter `[CTA]` (button / card): the outgoing mark shrink-fades exactly as the CTA scales up in its place. Because they share one `transform-origin`, the eye reads it as one element transforming, not a swap.
 - **Scene 3 (~2.4–3.4s) — approach.** A `[cursor]` arrives from off-stage on a **decelerating** path (it "arrives," it does not pass through) and lands a few px **off** the CTA's geometric center, so the aim reads human, not scripted.
 - **Scene 4 (~3.4–end) — press.** The cursor lands a physical CLICK — cursor and CTA compress together in lockstep, then release with feedback (an optional ripple / glow bloom). Holds on the clicked state.
+- **Variant — Hook (widget-morph opener)** (from `widget-morph-on-blank-field`;
+  reorders the beats — press first, morph second, title last). **(1) presence**: a lone
+  `[pill / chip lockup]` sits centered on a flat `[field]`; optionally the `[cursor]` glides in, a
+  hover pill-background appears behind the chip, and the click lands with the same lockstep press.
+  **(2) the morph**: the widget transforms IN PLACE — expands downward anchored at its top edge
+  into a `[menu]`, or spring-morphs outward into a `[prompt card]` with a small overshoot settle —
+  new content fades/slides into place. **(3) payload**: the transformed state performs —
+  `[placeholder]` types with a blinking caret, `[user text]` types while a control flips from
+  muted to its vibrant active color, or the menu snap-collapses back to the pill carrying the
+  `[new value]` + a checkmark pop; the background may snap to a new color under the persistent
+  foreground card. **(4) resolve**: the widget VANISHES; a plain frame closes the beat — a
+  `[closing title]` types on center, or a hold on the flipped solid.
 
-**motion vocabulary**: faint rotation-only resting breath (logo scope only); same-center morph-swap (shrink-fade ↔ scale-up sharing `transform-origin`); cursor decel-arrival from off-stage; off-center human aim; lockstep press compression; release feedback ripple / glow.
