P5 C verification against stacked B ce0fbb961721f734d162f019653216fb8dac0497

PASS gofmt -l . (empty)
PASS go build ./...
PASS go vet ./...
PASS golangci-lint run --timeout=3m --fast
PASS scripts/lint-file-length.sh (1813 Go files; zero grandfathered)
PASS go test ./config ./ui ./ui/theme ./internal/designtokens
PASS go test ./ui/overlay ./ui/tree ./ui/theme ./internal/designtokens
  Includes literal guard, all-role SGR tolerance, state/selection/metadata tests.
PASS Config edit round-trip for Light/Dark/System and legacy auto replacement
PASS go run ./scripts/gen-design --check
PASS container app driver: Test(Recovery|DesignDriverScenes|HelpTitleWithAndWithoutVersion)
  116 app goldens; four new appearance frames and four changed help frames.
  Source ANSI beside SVG for every gallery frame. Other 108 unchanged from B.
PASS role audit: every SVG cell pair uses generated roles within +/-1 channel.
  Full source constructor scan and AST state enumeration attached separately.
PASS AF_UPDATE_GOLDENS=1 make perf-container (refresh affected shared Config views)
  3 browser demo tests + 3-sample web and TUI perf pass. No budget changes.
  Only 14 Config/account web PNGs retained; unrelated timing shifts discarded.

Safety: host build/vet/lint and non-app/non-daemon unit tests only. App driver
runs inside af-p5-3916-b, created by make playtest-container-detached; perf uses
make perf-container. No host TUI, daemon/app tests, install/reset, shared tmux
teardown, other AF homes, daemon/theme.go edit or daemon ApplyTheme edit.

Self-review: all C code/tests/docs and affected stills inspected against the
interface design doc; state-mappings.txt enumerates inherited semantic axes
and C appearance resolution, migration, selection and help title behavior.

PASS strict MkDocs (PYTHONPATH=/tmp/p5-docs-tools python3 -m mkdocs build --strict)
PASS final make perf-container WITHOUT update mode: web/test-results/1558072-348e3c
  Three browser demo tests pass against committed goldens, web perf passes.
  TUI frame mean/max 79.734/88.021 ms; key-to-render 63.709/68.426 ms.
  All three raw samples explicitly checked <=480/351 ms. Budgets unchanged.
  Final raw metrics are in perf/. Earlier refresh run also passed; the initial
  comparison failed only on the new shared-manifest Config row before refresh.
