Every R3D_* read goes through r3d_env_has / r3d_env (env.ludic): a headless
build honours them as before, a windowed build only when R3D_DEV is set to
anything but "0", so a shipped game never reaches a debug view, feature kill,
file writer or hardware fake. Documented in docs/SHIPPING.md.

HDR output: an HDR10 swapchain (A2B10G10R10, ST 2084 over BT.2020) when the
setting asks and the display offers it, with HDR metadata. The tonemap's HDR10
variant keeps the SDR picture up to a 200-nit paper white and rolls highlights
on to 1000 nits; the overlay's converts the interface to the same white. The
screen and LDR images go 10-bit with it; screenshots refuse while it is on.
OpenGL and the Vulkan SDR frame are unchanged. The instance asks for
VK_EXT_swapchain_colorspace. HDR metadata only where the loader has
vkSetHdrMetadataEXT: Streamline's interposer does not, and calling the thunk
crashed the game the moment the swapchain came up HDR10. PC 4K monitor: HDR10,
validation 0. R3D_HDR overrides the setting.
DLSS:
- the vertical jitter offset flips with Streamline's image (rows from the top):
unflipped, Quality resolved the ground into concentric rings;
- preset K in every mode: the default M put Performance at 18 ms a frame at 4K
on an RTX 3070 Ti (33 fps against 41 with DLSS off; with K, 60);
- the camera is jittered only while this frame holds a token and the last
evaluate worked.
R3D_DLSS_PRESET, R3D_CAM_LOG (the camera and DLSS state a frame) and
R3D_NOGRAIN for measuring.

streamline.ludic: slInit before the Vulkan instance, feature support per
adapter, a frame token per frame, Reflex sleep and PCL latency markers, and
DLSS super resolution on the lit HDR frame (Halton jitter, depth + zero
motion vectors with camera motion from clipToPrevClip, matrices carrying
the Vulkan path's y flip and depth remap). Bloom, tonemap and sharpen read
the upscaled size. The device asks for privateData and present_id, which
Streamline's hooks need. R3D_DLSS / R3D_REFLEX / R3D_SL_LOG for tests.
gpu_feature_implemented: DLSS and Reflex.
ludic bundle (Windows): app native "<dir>" copies native libraries beside
the executable.
Verified on an RTX 3070 Ti: DLSS Quality evaluates 1280x720 -> 1920x1080.
