docs: cut CLAUDE.md to the rules it is for

CLAUDE.md had grown to 4,046 lines, ~3,300 of them per-component
write-ups: why a breakpoint is 500px, why a cap is a quarter, what a
spec once missed. Every session loaded all of it, and the rules that
apply to every change were buried among decisions that apply to one.

Those write-ups were already duplicated as comments beside the code
they describe -- every issue number they cite also appears in a code
comment -- so they are deleted rather than moved. What is left is the
tracker workflow, the commands, the verification tiers and a set of
broad engineering rules distilled from them, each pointing at where
its example lives. Three declined decisions recorded nowhere else go
to NOTES.md, and three code comments that cited CLAUDE.md sections by
name no longer do.

Closes #256

+## Declined, and recorded nowhere else (2026-09-25, #256)
+
+When CLAUDE.md was cut down to rules, most of its "considered and
+declined" paragraphs already had a home in a code or config comment
+beside what they explain. These three did not:
+
+- **`touch-action: manipulation` was declined** (#54). The 300ms tap
+  delay it is offered for is already absent on a `width=device-width`
+  viewport; what it would actually change is the gesture stack #63 tuned
+  by measurement on the reference device.
+- **There is no "Go to Genre"** in the phone row menu (#67). That menu
+  replaces name links a phone cannot use, and there has never been a
+  genre link to replace — it would be new navigation, which wants its
+  own issue.
+- **The overlaid queue has no tap-outside gutter on a phone** (#171).
+  The drawer-style gutter would buy the affordance by taking width off a
+  full-screen surface on a 424px viewport; back and a 44px close button
+  answer it instead.
