Page role: Theory and concept landing

Stability: Stable

Use this page when you want to browse the reference by concept rather than by class or module name.

Audience: Users who know the analytical question they are asking, but need the matching convention, theory note, or helper surface. Use this page for: Starting from concepts such as Fourier conventions, validation assumptions, spectral estimation, or compatibility layers.
