Web export: one sound button; the site demo starts silent and Try it starts with sound, each remembering its own choice; drop the attack hint the demo does not have

- camera.NewService and SetAccessibility; AttachWorld wires the accessibility settings
- tests/camera: priorities, blends, cuts, zones, follow, bounds, outputs, shake, zero allocations, BrainStep benchmark
- integration: rewind restores the camera state across a zone change
- camera2d.Adjuster passes the view by value (no per-frame allocation), D304 updated
- modules/camera/module.mk: test-camera in CI, bench-camera

-## Rules for engine code
-
-- **Modules talk through contracts.** A module never imports another module: shared types and services live in `contracts/` (`physics2d`, `camera2d`, `scriptcall`, `signals`, `debugdraw`, …). `tools/depcheck` enforces the import rules; an exception goes into `tools/depcheck/exceptions.txt` with its file and reason.
-- **Kernel stays neutral.** Kernel, editor and `sdk` never name a built-in module, its components or its diagnostic codes in string literals; names come from the module catalog.
-- **Every component has a Try it scene.** It lives at `res/docs/try/<Component>.aescene` (with `<Component>.aes` and prefabs next to it when needed), shows the component's own effect and runs without warnings; `aego docs check` fails without it.
-- **Internal state is not a component.** Controller state lives in unexported fields of the component it belongs to or in a world service. A component that exists only to carry state for a service is registered `Hidden`: it is not in Create, Add Component, Try it or the docs.
-- **Requirements add, they do not block.** Declare `Requires`; Add Component, `scene add-comp`, Paste and presets add the missing components in the same undo step.
-- **Every diagnostic code has a page with an example.** Component codes (`CAM`, `AUD`, `GMP`, `PHY`, …) also have an example scene that produces the code; `aego docs check` fails without one. Asset codes say `scope: asset`, codes that only an edit during Play produces say `scope: play`.
-- **Nodes are labelled, not pathed.** UI shows nodes with `props.NodeLabel` (icon and name, the path in the tooltip).
-- **Editor edits go through history.** Every edit is a history command, normally `commands.Mutation`, so Undo, the Play changes diff and agents see it.
-- **Hot paths do not allocate.** Systems, mixers and controllers allocate nothing per frame; add `testing.AllocsPerRun` checks and a benchmark next to new hot code.

 `engine/problems` collects `sdk.Diagnostic{Owner, Code, Severity, Message, Subject, BlocksPlay}` from sources with a revision; the service rebuilds the list only when a revision changes. `sdk.Diagnostics(ctx)` in `Init` returns the service; a module adds runtime diagnostics as a `sdk.ProblemSource` from `AttachWorld` and removes it in `DetachWorld`. The Problems panel shows them with the owner as category; an error with `BlocksPlay` stops Play (D210).
 
-Every code a module reports is listed in `Info.Codes` and has a page `res/docs/diagnostics/<CODE>.md` with front matter `code`, `title`, `severity` (`error`, `warning` or `info`) and either `example: <CODE>.aescene`, a scene next to the page that produces the code (with `<CODE>.aes` next to it when a script has to act, as for PHY007), `scope: asset` for codes that come from importing or checking an asset, or `scope: play` for codes that only an edit during Play produces (PHY006). `aego docs check` fails on a declared code without a page, a page whose code is not declared, a component code without an example, and an example that does not produce its code after `module.ValidateScene` and 60 headless frames. The pages appear under Reference → Diagnostics next to the script codes (D146, D316).
-
-### Contracts between modules
-
-A module never imports another module. What two modules share lives in `contracts/<name>` as plain types, a service ID and an interface; the provider registers the service in its world, the consumer looks it up with `engine.ServiceOf` and works without it.
-
-- **Provisions.** A value handed over at load time, keyed by a kind. `camera2d.AccessibilityKind` (`"camera2d.accessibility"`) carries the IDs of the Screen Shake and Reduce Motion settings: the settings module provides them with `r.Provide(camera2d.AccessibilityKind, camera2d.Accessibility{...})`, the camera module reads `ctx.Provided(camera2d.AccessibilityKind)` in `Init` and scales shake by them every frame.
-- **`physics2d.Queries`** (`physics2d.ServiceID`). Ray, point, circle and box queries; shape casts `CastCircle`, `CastBox`, `CastCapsule` and `CastBody`, which sweeps every non-trigger collider of a body and returns the first hit with its fraction, normal and, when the shapes already overlap, `Initial` and `Depth`; `Penetration` lists the overlaps of a body for depenetration; `BodyPose`, `BodyVelocity`, `MoveKinematic` (moves a kinematic body so contacts see its velocity), `Teleport`, `ApplyImpulse` and `Gravity`. `QueryFilter` selects layers and triggers; `SkipDynamic` ignores dynamic bodies, and `ExcludeNode` and `ExcludeBody` skip the caller's own collider or body. The gameplay controller is written only against this interface.
-- **`scriptcall.Caller`** (`scriptcall.ServiceID`). `Method(node, name, params)` finds a plain method by name in the scripts on a node and returns a `Ref`; `Call(&ref, args)` runs it. A hot reload starts a new `Generation`, which makes every older `Ref` stale: look the method up again when `Ref.Gen` differs. The State Machine finds its hooks this way.

 A module can give any of its components a live example on the documentation site: put a scene in `res/docs/try/<Component>.aescene`, named after the last part of the component ID (`try/Body2D.aescene` for `physics.Body2D`). The page of that component gets a Try it block that runs the scene in the browser with the Inspector, selecting the first node that has the component; a guide page can show a scene with `try: try/name.aescene` and `try_select: module.Component` in its front matter.
 
-Try scenes run on the docs runtime catalog (core, input, render2d, render3d, scripting, physics, debug, tween, cameras, gameplay, spawn, savegame and audio) with builtin assets only. A script `<Component>.aes` and prefabs `<Component>.<name>.aeprefab` (with their `.meta`) next to the scene are compiled and mounted with it. `aego docs check` loads each one, runs it for 60 frames and fails on a load error, a warning or a fault, and on a scene of a module outside the catalog.
