# The spectral analysis (magnitude_spectrum, note_of, detect_onsets). It used to pull in
# rustfft; the transform is now this crate's own (src/fft.rs: one f64 text, flowrs-math's
# twiddles, the same bits on every machine), so the feature costs no dependency. Kept so
# consumers that name it still build.

# num-complex is used at design time (f64 pole/zero placement for the IIR cascades) by the
# filter designers, for its arithmetic only: its transcendental methods run the platform's
# library, so the designers take theirs from flowrs-math (elliptic.rs csqrt, casin).

# Symposium (`cargo agents`): an agent working on a project that depends on this crate gets
# the flowRS skill (crates/flowrs-mcp/symposium/flowrs, rendered by flowrs-mcp's
# skills::symposium_plugin) and the flowRS MCP server under the read-only plan profile. Never
# the full profile: a dependency is not a trust root, and Symposium registers servers at user
# level. Symposium 0.5.1 parses a crate's MCP entry but does not dispatch it yet; a registry
# carrying symposium/flowrs/SYMPOSIUM.toml registers the same entry today.
