+# Grand Tourer — Evolution
+
+Open `nightdrive-evolution.blend` directly to edit the final source. The `Portfolio Evolution` scene contains individually editable bodywork, louvers, wheel vanes, wing and marker housings. The original source in the parent folder was not overwritten. No external assets or paid services were used.
+
+`export-grand-tourer.py` exports the loaded `Portfolio Evolution` scene into eight joined material groups, without lights, cameras, textures or animation. Execute it inside Blender with `__file__` set to the script path. The web renderer sanitizes Blender's duplicate-name suffixes before assigning its runtime lighting behavior.
+
+Design history:
+
+1. The original source scene was appended from `../nightdrive-grand-tourer.blend` and named `Portfolio Evolution`.
+2. `refine-grand-tourer.py` applied the first paint, hub, louver and deck-lip pass. This first pass is historical and should not be reapplied to the finished source.
+3. `add-personality.py` added the swept wing, mounted cyan guides and turbine wheel faces. This second pass replaces its own `signature-` objects on repeat runs.
+
+To reproduce from the original, follow that order in a separate scene. For ordinary editing, use the finished `.blend` and export script. Asset counts and provenance are recorded in `nightdrive-evolution.asset.json`.

+# Midnight grand tour
+
+Base: main 642f5b5, containing approved content/media and finished adaptive audio. Isolated branch: codex/gpt6-portfolio-evolution. Existing untracked work stays in the original checkout.
+
+## Visual grammar
+
+A continuous midnight highway, silver-blue bodywork, coral horizon, cyan interface accents. Retain the authored GLB and runtime terrain. Geist remains the self-hosted type family, now with open display composition and quieter supporting labels. Panels use a consistent 16px outer / 8px inner radius; controls use 8px. Keep the dark theme required by the night-drive identity. All approved wording, metadata, media, links, navigation and audio contracts are immutable for this pass, overriding generic design-skill copy and theme rules.
+
+## Scene and document ledger
+
+- Start: open name and equal roles on the left, rear three-quarter vehicle and low coral sun on the right. Lower, longer lens establishes scale.
+- Profile: world shifts left to leave a calm reading surface on the right.
+- Experience: world shifts right; broad timeline with clear supporting operations grouping.
+- Infrastructure: centered panorama behind a wide architectural plate, generous diagram nodes and a distinct operations case.
+- Selected builds: broad media-first staging. Portrait screenshots become a carefully spaced three-screen presentation; Footy Tracker receives an evidence-led split composition because no screenshot is approved. All captions and evidence remain readable.
+- Additional work: a two-column compact collection instead of another narrow rail.
+- Toolkit: horizontal groups with larger recognizable technology marks.
+- Contact: camera settles right, warmer horizon, clear destination with unchanged contact actions.
+
+Use render-only camera endpoints and smoothing; never change canonical journey state or audio inputs. Geometry, lights and shader materials remain persistent. Preserve current native scrolling, sign contract, quality governor, resource disposal and fallback.
+
+## Implementation and verification
+
+Work in existing Vue / native CSS / Three.js. No new dependencies. Build on the existing scene and components. Add a focused presentation stylesheet and camera ledger, improve sun/terrain/lighting, and keep semantic markup unchanged wherever possible. Inspect the compiled, validated preview across desktop, tablet, phone and short sizes; exercise navigation, scroll/reversal, resize, static/reduced motion and audio controls. No test edits. Run existing build checks once, then typecheck/client/SSR/prerender/artifact/transfer checks after implementation. Record actual observations and limitations.

+# Midnight Grand Tour — visual review
+
+Implemented on `codex/gpt6-portfolio-evolution`, based on main `642f5b5`, in `.worktrees/gpt6-portfolio-evolution`. Local preview: http://localhost:41812. Ready for visual review; not merged or deployed.
+
+## The visible changes
+
+The opening now combines an open typographic introduction with a longer-lens night drive. A larger coral horizon, broad cyan mountain waves and cooler metallic reflections establish one visual language. Camera compositions ease between chapters without changing native scrolling or the canonical journey/audio state.
+
+The Blender-authored car retains the original wedge body, now with a swept floating wing, turbine-style wheel faces, rear-window louvers, segmented coral lamps and cyan rear guides. The editable source and provenance live in `assets/blender/evolution/`. It exports into eight material groups and 18,564 triangles; reflections are baked once into a small procedural environment, with no per-frame reflection pass.
+
+The professional material has more space: a broad career timeline, an architectural infrastructure plate, larger real project screenshots, an evidence-led Footy Tracker layout, and clearer toolkit groups. Project images open at full size. Controls keep their existing behavior, with refined spacing, focus and touch states. Static and reduced-motion visitors receive desktop or phone artwork captured from the real world.

+
+## Preservation and practical checks
+
+- Normalized rendered main text is identical to the freshly built approved baseline: 12,333 characters. Original content links match. The eight section IDs and their order are unchanged.
+- Content, approved metadata, audio source, canonical journey source and test files have no changes. All compiled approved project media and audio files match the baseline byte for byte.
+- Final typecheck, client build, server build, validated prerender, artifact validation and transfer-budget check passed. No budget limits were changed. The initial baseline build also ran the required existing unit suite: 662 checks passed; it was not repeatedly rerun during visual iteration. No tests were added or edited.
+- Inspected all chapters at desktop 1440×900, tablet 768×1024, phone 390×844, narrow 320×568 and short 1024×600. No horizontal overflow was observed. Exercised menu navigation, scroll, fast jumps, reversal, resizing, keyboard scrolling and focus states.
+- Soundtrack reached the running state; mute/unmute, volume at 25%, pause/resume motion and graphics selection worked. Static mode, system reduced motion and a no-JavaScript browser retained content and appropriate poster artwork. Full-size project-image navigation worked.
+- The final direct preview produced no JavaScript errors or console warnings, including after graphics-quality changes. Resetting texture-upload flags between renderer generations fixed the observed WebGL warning.
+- Final compressed-transfer totals: initial application 90,134 bytes; first live scene including the car 279,010 bytes; both fallback posters together 189,323 bytes. All transfer checks passed. Detailed totals are in `evidence/gpt6-evolution/transfer-budgets.json`.
+
+## Practical limits
+
+The inspection browser reports ANGLE/SwiftShader software rendering. A short direct Low-quality sample averaged about 12 fps at 1440×900 and 40 fps at 390×844; an instrumented High-quality sample was slower. These are software-renderer measurements, not a hardware-GPU performance certification. Existing adaptive quality and Static controls remain available. Vite still reports the existing large deferred Three.js chunk warning; the measured compressed scene transfer remains within its budget.
+
+The recording shows actual browser output and is silent. Audio controls and preservation were checked separately; no claim is made of a complete auditory mix review or physical-device testing.
