docs(s-view): spec the r11 Sample-face recomposition (knob deck, curve popup, full-width hero) for Wave B

Adds S-VIEW-11/12/13 to PLAN, r11 addendum, and forks R11-F1 (window default height) + R11-F2 (Zone-panel knob parity) for Daniel.

+### Phase S editor Wave B — Sample-face recomposition (r11; Daniel, 2026-07-27)
+
+> Daniel's post-landing DAW pass on the S-VIEW editor: **all linear sliders → small radial
+> knobs** grouped into a fenced knob deck (envelope controls grouped as a unit); the **mode
+> toggles compact**, not full-width; the **inline velocity-curve box → a miniature curve
+> preview button + full-size popup editor** (right-click deletes a node in the popup); the
+> **hero waveform full-width**. A pure view recomposition — zero engine/state/persistence
+> change, VST3 class UID unchanged. Authoritative layout spec: **CONTEXT.md §S-VIEW → "The
+> Sample-face recomposition (r11)"** (band order, group taxonomy, cell metrics, popup
+> geometry, inventory contract — nothing silently dropped). Product framing:
+> `docs/product/midi-playback.md` §Addendum r11. **GATED on the knob-primitive track**
+> (separate, in flight) — S-VIEW-11/12 consume the primitive, they do not build it.
+> All drawing through the L1 kit; all layout/hit-test in pure geometry modules.

+- [ ] **S-VIEW-11 — the knob deck.** Pure **`knob_deck`** (group boxes + caption rows +
+  compact-toggle rects + knob-cell rects + deterministic group wrap + hit-test; mirror of
+  `action_bar`/`param_slider`; unit-tested) + shell: the Sample control strip becomes three
+  fenced groups — **AMP ENVELOPE** (Gate|Trigger caption toggle; Attack·Hold·Decay·Sustain·
+  Release or Fade In·Length %·Fade Out knobs, 5-cell width reserved so mode flips never
+  reflow), **PITCH** (Varisp|Preserve caption toggle; Key Track knob), **PITCH ENV** (Off|On
+  caption toggle; P.Attack·P.Decay·P.Depth knobs, Disabled-not-hidden when Off). Slider rows
+  + full-width toggles retire from the Sample face; the hero becomes the elastic band
+  (bottom-anchored fixed deck). Preview-velocity slider becomes a cluster knob cell (same
+  persisted seam).
+- [ ] **S-VIEW-12 — curve popup + full-width hero.** Pure **`curve_popup`** (sheet/close/box
+  geometry + outside-sheet dismissal test; mirror of `overflow_menu`; unit-tested) + shell:
+  the inline velocity-curve box leaves the hero band (**hero runs full width**, S11 markers +
+  envelope overlay unchanged); a **28×28 miniature curve preview button** lands immediately
+  right of the preview-velocity knob (live miniature trace; Active while its popup is open);
+  click opens the **centered popup** hosting the full-size curve editor — all landed
+  interactions preserved (drag, click-add, Alt-click delete, drag-off delete) **plus NEW
+  right-click node delete** (endpoint-guarded, commits like Alt-click). Dismiss: Close ×,
+  outside-click (no drag in flight), Esc.
+- [ ] **S-VIEW-13 — Zone-panel parity (gated on fork R11-F2).** The Zone param panel adopts
+  the same knob deck + curve-preview-button/popup; retires `param_slider`'s slider rows
+  outright (one control grammar on both surfaces of the one storage site).

+**Open forks (Daniel's to call before Wave B builds)** — recorded in the CONTEXT.md §S-VIEW
+fork ledger: **R11-F1** hero height vs. default window (lean: elastic hero, keep 840×620);
+**R11-F2** Zone-panel parity (lean: yes — one grammar).
