The fused-fragment check in lib.rs cannot see a detail pass: it is a
separate shader composed at a resolution compose() never knows. The
kernel's own test now scans the block the composer wrapped, with comments
stripped so prose about the keyword cannot fail a test about the code.

Capture sharpening as a two-pass unsharp mask in the detail stage: blur
along x, then along y, each pass applying a one-dimensional high-pass to
luminance so the composite preserves a flat field exactly and matches the
textbook kernel on any locally one-dimensional edge.
The radius is stated in source pixels and converted once per render, so a
radius tuned on a fit view is the radius the exported file gets. Below one
render pixel the operation declines to draw rather than showing sharpening
the file will not contain, and emits a single pass-through that still
carries the output transform.
The develop session now renders through render_detailed, which is what
lets an active neighbourhood operation reach the screen at all.

Checkpoint committed by the coordinator, not by the authoring agent: the
session hit its API limit mid-task and left this work uncommitted. Committed
so it survives, NOT because it is finished - expect failing tests and
half-applied changes. The agent resumes from here.
