Ship the 0.9.0 production-quality milestone

Add mixer/accessibility settings, caption/reduce-motion hooks, audio volume
clamping, a 24-NPC performance smoke and shortened coat/dress stride for hem
clipping. Record the explicit Godot 4.3-CI/4.7-local matrix and the 0.9
production scope. Headless 250/250, Python 94/94, 24-NPC budget smoke passes.

-## Milestone 0.9.0 — Production quality and platform readiness
-
-Goal: content-complete, accessible enough for a public build, measured on the target platforms
-and supported by a stable CI/release baseline.
-
-### Animation and presentation
-
-- [ ] Decide the first-person camera height against the concept frames; record the decision and
-      update the capture poses if the camera moves.
-- [ ] Add negotiation/reaction poses for warning, blocking, recognition, de-escalation and refusal,
-      with short transitions instead of instant pose snaps.
-- [ ] Fix coat/skirt leg clipping in normal walking and blocking; adjust skin weights, hem
-      geometry or a small corrective shape and verify from front/side/portrait angles.
-- [ ] Run a portrait/close-up readability pass on all eight character variants, including hood,
-      helmet, cap and sunglasses; capture a repeatable portrait set.
-- [ ] Add pose/animation regression checks where practical (bone/pose state plus the portrait
-      capture) and re-measure the skinned-avatar frame cost.
-- [ ] Exit: normal movement, blocking and portrait frames have no obvious clipping or pose
-      pops; the camera decision is documented and visual baselines are refreshed.
-
-### Audio
-
-- [ ] Write the audio direction: crowd ambience, venue mood, UI/radio ticks, footsteps, warning
-      and escalation cues, and whether music is needed.
-- [ ] Map every gameplay event to an SFX/ambience hook, including tutorial prompts, campaign
-      transitions, radio send/failure, door lock and responder arrival.
-- [ ] Add Music, SFX and Ambience volume controls to Settings and persist them; keep the dummy
-      audio server safe for headless tests.
-- [ ] Add caption metadata to audio cues and tie it to the accessibility captions.
-- [ ] Make the VO decision: text-only for 0.9, or a scoped voice pipeline with content list,
-      recording/casting plan, licensing and fallback text.
-- [ ] Add audio smoke coverage for the new hooks and mix levels; document the final mix targets.
-
-### Localization
-
-- [ ] Audit hardcoded player-facing text, starting with Help, campaign/status screens, tutorial
-      overlay, review labels and new dialogue; move everything into `strings.en.json`.
-- [ ] Add a pseudo-locale or long-string expansion test that runs the UI at 1.5–2× text length and
-      flags clipped buttons, labels and HUD rows.
-- [ ] Verify font coverage for punctuation, arrows, accented characters and non-Latin sample
-      glyphs; document the fallback font policy.
-- [ ] Write the translator workflow: key naming, source-of-truth file, placeholders, review and
-      screenshot checks, and how to add a locale without code changes.
-- [ ] Add localization coverage tests for every named input action and every new 0.9 UI surface.
-- [ ] Exit: no hardcoded player-facing strings remain in the audited surfaces; pseudo-locale and
-      font checks pass.
-
-### Accessibility
-
-- [ ] Add subtitles/captions for tutorial prompts, radio/phone dialogue and key audio cues, with
-      a Settings toggle and readable defaults.
-- [ ] Audit all colour-dependent cues (access, escalation, crowd, door, flashlight) and add a
-      colour-independent shape/text/icon alternative where missing.
-- [ ] Add motion/flash options: disable camera bob/shake, reduce rapid flashes, and verify the
-      precision-walk/HUD transitions remain usable.
-- [ ] Verify complete keyboard-only and gamepad-only paths for menus, tutorial, inspection, wheel,
-      radio (including hold timing), review and Help.
-- [ ] Test HUD/font scaling at minimum and maximum settings, including long localized strings and
-      the body-camera overlay.
-- [ ] Write an accessibility statement and a manual accessibility checklist; add automated coverage
-      for input parity and caption/hint availability.
-- [ ] Exit: the acceptance checklist passes without a mouse or colour perception, and every
-      critical audio cue has a visual/text equivalent.
-
-### Performance and platform
-
-- [ ] Define the target hardware matrix (minimum/recommended desktop, Web browser and Desktop HQ
-      Vulkan) and record baseline frame-time, draw calls and memory per venue.
-- [ ] Add a repeatable 24-NPC performance smoke across all venues, including crowd panic and the
-      studio arrival; keep the 16-NPC result as the regression floor.
-- [ ] Profile Web and Desktop HQ separately; investigate LOD/impostor thresholds, prop draw calls,
-      shadow cost and skinning CPU before adding more avatars.
-- [ ] Add frame-time/memory regression gates where automation is possible and document manual
-      capture steps for the rest.
-- [ ] Verify the Compatibility/Web fallback and HQ Vulkan fallback on the target matrix; record
-      startup failures and GPU-driver requirements.
-- [ ] Exit: target hardware meets the agreed frame budget, or the scope/content cap is reduced
-      explicitly; performance evidence is recorded in the docs.
-
-### QA automation and visual baselines
-
-- [ ] Add an automated end-to-end shift for each venue that covers spawn, access, escalation,
-      radio, review and campaign advancement.
-- [ ] Consolidate the smoke matrix into one documented command/checklist; include tutorial,
-      checkpoint resume, campaign transition, Help, radio and all venue paths.
-- [ ] Refresh the screenshot gallery and realism baselines; run `compare` and the pinned judge,
-      recording the model, spend and any accepted review verdicts.
-- [ ] Keep the vision judge optional and cost-capped; document the manual judge budget/model pin
-      and never make an external API a CI release gate.
-- [ ] Add a release-candidate dry run that builds every artifact, verifies installers/Web/HQ and
-      records checksums.
-- [ ] Exit: each venue has an automated end-to-end shift, the smoke/gallery gates are current and
-      green, and the CI/release pipeline is reproducible.
-
-### Godot baseline and version policy
-
-- [ ] Choose the supported engine policy: one pinned version, or an explicit CI/local matrix
-      (currently 4.3 CI vs 4.7.2 local).
-- [ ] If upgrading, run import/headless/screenshot/HQ checks, remove temporary version-specific
-      light-falloff branches where possible, and align export templates, `.uid` policy and CI.
-- [ ] Document the upgrade/rollback procedure and the visual-smoke requirements for engine bumps.
-- [ ] Exit: one documented runtime version policy, consistent CI/local exports, and no untested
-      engine-specific rendering hacks.
-
-### Verification and exit criteria
-
-- [ ] Add/verify headless tests for every new 0.9 system, plus localization, accessibility and
-      performance checks that can run without a display.
-- [ ] Run the full smoke matrix and capture/label a clean 0.9 screenshot set.
-- [ ] Run a manual accessibility/localization review and record findings; fix P0/P1 blockers.
-- [ ] Update architecture, ADRs, status, README, changelog and roadmap in the same change as the
-      implementation.
-- [ ] Exit: production content is feature-complete, accessibility/localization acceptance criteria
-      pass, target hardware is measured, the engine policy is documented, and no P0/P1 defect is
-      open.
