v0.18.0

v0.18.0 (2026-08-20)

Feat

• pwm: MOD is an attack and a decay inside the pulse
• copy: channel -> channel carries the channel's own settings

Fix

• ci: keep newlib, and let a failed ARM build fail its own step
• fram: come back on the last patch, not on the defaults
• dac: let the ramp span be a guess, and stop compensating for it

Perf

• dac: two substeps, where the engine has the headroom for them
