manutej Sheaf enhance
Read HANDOFF.md before writing code. Work on branch enhancement. One concern per PR.
Invariants (stop if you break one)
- Diffuse does not increase Dirichlet energy; known stalks do not drift.
- Residual scale is diverging teal → terracotta. Size = dim. Hue = ordered level. No rainbow.

Code map
Algebra stays in src/lib/sheaf/ and stays testable without React.
State lives only in src/store/sheaf.ts.
Every new control needs a HINTS entry in src/components/sheaf/chrome/Hint.tsx.
Definition of done (HANDOFF §10)
A stranger can drop JSON, see energy + uniqueness, switch Strata/Slice/Multiples/Matrix, name a terracotta edge in domain words, Diffuse, Close, export residuals, and do it at 390px.
