document.createEvent('CustomEvent') was returning a generic Event,
so the legacy DOM Level 2 pattern
var e = document.createEvent('CustomEvent');
e.initCustomEvent('foo', true, false, payload);
threw "TypeError: e.initCustomEvent is not a function" because the
returned object was an Event, not a CustomEvent — and CustomEvent
didn't define initCustomEvent anyway. The Starbucks China bundle
(and a long tail of other CDN bundles using the same shim) depended
on this and aborted bootstrap.
Two changes in crates/obscura-js/js/bootstrap.js:
1. Add CustomEvent.prototype.initCustomEvent(type, bubbles, cancelable,
detail) matching the spec.
2. Rewrite Document.prototype.createEvent so it dispatches to the
right class based on the type string ('CustomEvent', 'MouseEvent',
'MouseEvents', 'KeyboardEvent', 'FocusEvent', 'InputEvent',
'UIEvent', 'WheelEvent', 'PointerEvent', 'ErrorEvent',
'PopStateEvent', 'AnimationEvent', 'TransitionEvent', and
case-insensitive 'Events' aliases). The HTMLDocument variant on
the second Document class delegates to the canonical impl.
Spec note: createEvent returns the event with an empty type until
init*Event() is called — matched exactly.
Four new unit tests cover initCustomEvent presence and field setters,
class dispatch for CustomEvent / MouseEvent / MouseEvents / KeyboardEvent,
and the unknown-type fallback to Event.

jQuery DataTables references the standard CharacterData interface which
was undefined in obscura's DOM environment, causing ReferenceError and
empty page renders.
- Add CharacterData class extending Node with data/length/substringData/
appendData/insertData/deleteData/replaceData
- Make Text and Comment extend CharacterData instead of Node
- Update _wrap() to create proper Text/Comment instances by nodeType
- Add create_comment_node op for Document.createComment()
- Fix set_text_content to handle Comment node mutations

Fixes#1: replace unwrap() panics in run_multi_worker_serve with match on the Result.
Fixes#2: route /json round-robin via worker_port instead of hardcoded port+1.
Fixes#3: return 502 Bad Gateway when a worker is unreachable instead of silently dropping the connection.
Fixes#5: thread --stealth through start_with_options -> CdpContext -> BrowserContext::with_options so the flag actually has an effect in serve mode (was let _ before). Log message now reflects the actual capability based on the stealth cargo feature being compiled in.
Fixes#15: try/catch the parentNode assignment in the attachShadow polyfill so it doesn't throw a TypeError against the read-only Node.parentNode getter (Cloudflare Turnstile triggers this path).
Brings Obscura's CDP server in line with what Playwright's
`chromium.connectOverCDP()` expects. Each fix is small and surgical;
together they make `connect → newContext → newPage → goto → page.title()`
work end-to-end against `https://example.com`.
1. **server.rs — emit pending events before command response.**
Chromium CDP semantics require side-effect events (e.g.
`Target.targetCreated` + `Target.attachedToTarget` from
`Target.createTarget`) to arrive *before* the originating command's
response. Playwright's wire reader assumes this ordering — it
resolves the response promise on the response and then synchronously
looks up the freshly-created session. Reversing the order makes that
lookup miss and the page hang at `newPage()`.
2. **domains/browser.rs — accept Browser.setWindowBounds as a no-op.**
Playwright calls `Browser.setWindowBounds` during teardown. Returning
"Unknown Browser method" causes Playwright to treat the target as
broken and tear it down mid-test, surfacing as "Frame has been
detached" on the next `page.title()`.
3. **obscura-browser/page.rs — frame_id == target_id for main frame.**
Was `format!("{id}.1", id)`. Playwright's frame manager indexes
frames by frame id and looks up the main frame by target id, so the
`.1` suffix made every main-frame lookup miss.
4. **domains/page.rs + dispatch.rs — track isolated worlds and re-emit
them post-navigation.** Playwright registers a utility world via
`Page.createIsolatedWorld` and expects `Runtime.executionContextCreated`
for each registered world after every navigation. Without re-emission,
the utility-world handle goes stale post-`goto` and `page.title()`
hangs waiting for the world's execution context. Falls back to the
legacy `__puppeteer_utility_world__24.40.0` name when no worlds have
been registered, preserving prior Puppeteer support.
5. **obscura-js/runtime.rs — strip trailing semicolons before wrapping.**
Playwright's utility-script expression is an IIFE ending in `})();`.
Both `wrap_expression` (CDP `Runtime.evaluate`) and `evaluate_for_cdp`
(the `meta_code` IIFE) embed the user expression inside `({EXPR})` /
`return ({EXPR});`. With the trailing `;` left in, this produces
`({...;})` — a SyntaxError. Parse errors are not catchable, so the
surrounding try/catch never fires and the call silently returns
`undefined`, surfacing as `page.title() === ""`.
Verified end-to-end against `https://example.com`:
[probe] connect OK
[probe] newContext OK
[probe] newPage OK
[probe] goto OK
[probe] title = Example Domain
Allow loading local HTML/CSS/JS files via the file:// protocol,
enabling Obscura to be used for testing static sites without
running a local HTTP server.
Changes:
- Allow "file" scheme in validate_url() and validate_fetch_url()
- Add fetch_file_url() to read local files and return synthetic
HTTP responses with appropriate content-type headers
- Skip private IP / localhost checks for file:// URLs
