Visual presets and demo polish

All fifteen examples share Controls (F2) → Devices → Visual style. Use the page arrows to reach the second Devices page. Authored preserves each game's palette. Warm shifts toward ochre; Cool emphasizes teal; Ink uses a blue-grey luminance palette. The choice saves on the current device, separately for each game. Existing version-1/2 preferences load with Authored; version 3 adds style. Version 4 adds independent resolution, shadow and local-light preferences; older settings retain their saved choices and use the new detail defaults.

Every browser example also has a Details button beside Controls. Its shared panel pauses play and saves choices for that game on this device. Lighting, resolution, shadows, local lights and visual style can be adjusted separately. Controls that the example's renderer or scene cannot use are disabled. Reset details restores these five choices without changing audio or input bindings.

The browser accepts ?look=authored|warm|cool|ink and ?quality=low|medium|high. These explicit session overrides take priority over saved settings without overwriting them. Remove the query to use saved settings. For windowed native games, set FERRAVEX_LOOK and FERRAVEX_QUALITY to the same names. Courtyard and Orbit Breaker's headless exporters accept FERRAVEX_LOOK; quality changes do not accelerate those CPU reference renderers.

Mobile fullscreen and touch

Every browser game has a Fullscreen button alongside Details. It requests native fullscreen, including the toolbar so Exit and settings remain available. On touch devices it requests landscape for wide games, and portrait for Orbit Breaker and Salvage Pinball. Orientation is unlocked when fullscreen ends. Browsers may reject either request: the gallery then expands the existing iframe to the browser viewport without restarting the run. Browser bars can remain in this fallback. A rotation hint appears if the viewport does not match the game; the canvas is never visually rotated away from its input coordinate system.

Exit returns to the embedded player and restores page scrolling. Escape also exits the expanded fallback. Text selection, touch callouts, drag selection and tap highlighting are disabled inside the game/player only; scene-editor text fields and the documentation remain selectable. Resizing, rotating or losing pointer capture releases held input to prevent stuck movement or braking.

Fullscreen/orientation behavior is browser-dependent. Contract tests exercise native/fallback transitions and denied orientation requests; physical iPhone testing is still required.

Rendering cost and boundaries

These are lightweight palette shader presets, not full-screen post-processing. Retained GPU draws apply the palette after the material hook and lighting/fog. Immediate primitives use the matching CPU transform; the two software examples use the same palette definitions. No additional texture, render target or draw pass is required. The original flat face normals and alpha remain intact. Emissive sprite effects retain their authored accent colors.

set_camera enables world palettes. set_default_camera restores neutral HUD colors. Games drawing both in screen coordinates can call set_world_colors(true/false) at their world/HUD boundary. Built-in menus, health, ammo, objectives and instructional text remain readable in every preset. Custom shaders still support transactional editing and graphics recovery; presets do not replace those hooks. See materials.

Browser resolution defaults to the device pixel ratio, up to 3×, independently of lighting quality. This keeps a low-lighting game sharp on a high-density phone. Details offers explicit 0.75×, 1×, 1.5×, 2× and 3× choices. Framebuffers are bounded to eight megapixels and the smaller of the driver limit and 8,192 pixels per dimension. Lower resolution reduces GPU work; 3× renders nine times as many pixels as 1× at the same CSS size. These limits do not change gameplay coordinates, input sensitivity, simulation ticks or network rates. Orbit Breaker keeps its fixed-resolution CPU canvas and only exposes visual style.

With shadows and lights set to Follow preset, Low disables dynamic sun shadows and selects at most two point lights; Medium/High use the limits in lighting. Separate overrides select no shadows, 512-pixel hard shadows or 1,024-pixel soft shadows, and zero, two, four or eight local lights. Scenes must author a sun or point lights to use those settings. Courtyard uses the same shadow tiers. Dune Skimmer uses blob shadows only when dynamic shadows are disabled, including when using an explicit override.

Marble Run keeps its overhead follow distance beside poles. Its open course does not shorten the camera boom against gameplay colliders. Narrow viewports use a two-row HUD and touch controls sized to the available play area.

Geometry and shadows

Mesh3d::combine bakes valid, opaque, untextured static pieces into a bounded mesh at load time. It transforms positions and inverse-transpose normals, corrects reflection winding, and rejects singular transforms, bad indices, transparent pieces and more than 65,535 vertices. Group nearby pieces so the combined bounds remain useful for culling. Crystal Cavern uses 3×3-tile chunks after its original vertex AO bake, removing wall faces fully hidden by solid neighbors after baking. This reduces draw calls but can submit extra triangles at chunk edges; measure the tradeoff for the scene.

The shared native/browser shadow depth passes use slope-scaled polygon offset in addition to the existing normal/depth bias. Strike removes overlapping baked shadow quads and separates container ribs from their base surfaces. Its pistol, rifle and sniper use separate original silhouettes and muzzle offsets. draw_skinned_viewmodel draws an animated foreground prop after the world using the current perspective and lighting, with depth testing and world shadow participation disabled. Following draws retain their camera/depth state.

Courtyard reuses its CPU framebuffer/depth/scratch storage between frames. Orbit Breaker fills opaque rectangles by row. The shared browser retained host reuses shadow uniform buffers and rebuilds shader-error summaries only when material status changes. These improvements retain the existing gameplay rules.

See performance for measured costs and open regressions. Linux and the available browser are the measured platforms; no low-end physical device, Windows/macOS runtime or iOS result is implied.
