Like CSS Grid, Servo's `Preferences::default()` ships
`layout_variable_fonts_enabled: false`. `Servo::new` forwards it to Stylo
(`layout.variable_fonts.enabled`), and with the gate off Stylo ignores
`font-variation-settings` and variable weight/width axes: a variable font
renders only its default instance, so every requested weight looks
identical. Modern sites lean on variable fonts (Inter, Roboto Flex,
system New York/SF), so text rendered at the wrong weight versus Chrome.
servo-fonts already drives variations through HarfBuzz, so enabling the
pref is the real fix. Verified with a `@font-face` page using a variable
font at `font-variation-settings: "wght" 200` vs `"wght" 900`: identical
weight before, distinctly light vs black after.
runtime.rs 473 lines (<500). fmt/audit/clippy clean; software_host real-
Servo test passes.

The workspace lints deny `clippy::unwrap_used` and `clippy::panic`, but
`command.rs`'s two unit tests used `.unwrap()` and `panic!`, so
`cargo clippy --workspace --all-targets -- -D warnings` (a CI gate)
failed on them. Convert both to the crate's Result-returning test
convention: `CommandIntent::parse(...)?` instead of `.unwrap()`, and a
`return Err(...)` in the let-else instead of `panic!`. Same assertions;
`DomainError` is `thiserror::Error`, so `?` flows into `Box<dyn Error>`.
Workspace clippy --all-targets now reports 0 errors.

The `sed`-based extractions in the preceding three split commits each
left one extra blank line at the cut boundary, which `cargo fmt --all
--check` (a CI gate) rejects. Whitespace only — no code change.

`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).

`gpui_harness_tests.rs` was the repo's largest file (1062 lines) and the
worst violator of the 500-line / no-god-component audit. Its 13
`#[gpui::test]`s each build their own local fixtures and share only a
pair of type aliases, an `impl super::ElyShell` test helper, and two free
fns (`active_tab_overlay_state`, `example_url`).
Keep those shared items plus tests 1-4 in the root module; move tests 5-8
to `gpui_harness_tests_b.rs` and tests 9-13 to `gpui_harness_tests_c.rs`,
each opening with `use super::*;` so they inherit the parent's imports
and shared items with no per-item churn. Declared via `#[path]` mod, the
established sibling-test pattern in this crate.
475 / 319 / 276 lines. No tests added, removed, or renamed (paths gain a
`gpui_harness_tests_{b,c}::` segment). clippy --all-targets -D warnings
clean; `cargo test -p ely_app` 167 passed / 0 failed.

`scripts/audit_source_lines.sh` (a CI gate) flagged `tests/commands.rs`
(527) and `tests/splits.rs` (524) over the 500-line ceiling. Both are
flat lists of independent `#[test]` fns with no shared helpers, so each
splits cleanly into a sibling integration-test binary (the crate already
uses a topical file-per-concern layout under `tests/`).
- commands.rs (29 tests) -> commands.rs (20: tab/space/profile/search)
+ command_pages.rs (9: internal-page-opening commands). 527 -> 389.
- splits.rs (25 tests) -> splits.rs (13: layout/axis/detach mechanics)
+ saved_split_lifecycle.rs (12: close/archive/restore/group). 524 -> 266.
No tests added or removed; each new file carries only the imports it
uses. `cargo clippy -p ely_browser_core --tests -- -D warnings` clean;
all ely_browser_core tests pass.

`runtime.rs` had grown past the 500-line ceiling enforced by
`scripts/audit_source_lines.sh` once the grid-pref comment landed (522
lines). Peel the repaint/present pair — `paint_without_readback`,
`paint_without_readback_with_completion`, the private `paint_webview`,
and `paint_with_readback` — into a sibling `runtime_paint.rs`, exactly
the `paint.rs` boundary the embedding architecture doc prescribes.
`runtime_paint` is a child module of `runtime` (declared via `#[path]`,
mirroring `runtime_context`), so it keeps access to the private
`SoftwareServoHost` fields and the `webview()` / `wait_for_paint_completion`
/ `read_rendered_frame` helpers without widening any visibility. No
behaviour change: public API and call sites are identical.
runtime.rs 522 -> 469 lines. Build + clippy clean; full workspace test
suite green.

`Preferences::default()` is Servo's conservative library default and
ships `layout_grid_enabled: false`. `Servo::new` forwards prefs to Stylo
(`prefs::set` -> `stylo_static_prefs::set_pref!("layout.grid.enabled")`),
so with the gate off Stylo blockifies `display: grid`: every grid
container collapses to `display: block` and grid-based page layouts
stack into a single column — the "broken" rendering reported on modern
sites.
`ely_servo_preferences()` only flipped `dom_intersection_observer_enabled`
and inherited the grid default, so ELY rendered grid pages collapsed
while Servo's own servoshell (which enables the pref) renders them
correctly. The layout path is implemented — servo-layout drives
`DisplayInside::Grid` through Taffy — so enabling the pref is the real
fix, not a workaround.
Verified with a deterministic `display: grid; grid-template-columns:
1fr 1fr 1fr` page: 9 stacked full-width bars before, a 3x3 grid after.
Wikipedia/HN/GitHub/google.com re-checked unchanged; full workspace
test suite green.

Servo's \`WebView::set_history\` fires \`notify_url_changed\` on **every**
history mutation — full navigations, redirects, in-page link clicks,
and JS-driven \`history.pushState\` / \`history.replaceState\`.
Our pipeline fans that delegate signal back through
\`WebSurfaceUrlChange\` into \`tab.url\`. The next \`ensure_surface\`
observes the new tab URL, hashes a fresh ensure key, and calls
\`ServoLiveClient::ensure\` → \`apply_navigation\`. Until this commit
\`apply_navigation\` compared the request against the local
\`session.requested_url\` cache and, on mismatch, sent Servo a
\`webview.load(url)\` — even when Servo was the one who *just*
told us about that URL.
\`WebView::load\` is a hard navigation: it tells the constellation
to abort the current document, clear the surface, and refetch.
google.com's homepage \`replaceState\`s a fresh \`?zx=<timestamp>\`
roughly once a second to bust caches; with this round-trip we
were turning each of those into a full load-clear-refetch and
producing one visible white flash per second.
Use \`host.snapshot(webview_id).url()\` (which Servo keeps in lock-step
with \`set_history\`) as the source of truth. If Servo's WebView is
already at the requested URL, just sync our \`session.requested_url\`
bookkeeping and return — no \`load\` message, no surface clear, no
flash. Genuine embedder-initiated navigations (chrome URL bar typed,
in-app link click) still take the \`should_navigate\` path because
Servo's URL hasn't caught up to the requested target yet.
