`web_surface_live_site_tests.rs` (648, behind the `live-site-smoke`
feature) was the last file over the audit ceiling. Its helpers split
cleanly one-directionally: drivers/waiters call the leaf
validators/builders, never the reverse.
Keep imports, consts, the 6 tests, `run_isolated_live_site_test`, the
`assert_*` drivers, `render_web_surface_frame`, and the `wait_for_*`
helpers in the parent; move the leaf validators + pure fixtures
(`ExpectedCssViewport`, `validate_prd_frame*`, `log_prd_frame`,
`require*`, `*_bounds`, `live_scroll_point`, `web_tab`, `normalized_url`)
into `web_surface_live_site_support.rs` as `pub(super)` items, opened
with `use super::*;`. Parent pulls them back via `use ...support::*`.
470 / 184 lines. `cargo build/clippy -p ely_app --tests --features
live-site-smoke -- -D warnings` clean. scripts/audit_source_lines.sh now
exits 0 (every source file <= 500).
