+**The meadow's grass draws on the Vulkan renderer again** — the chunked grass path uploaded its `vec4` tile
+table with `u_fv`, which on Vulkan copies one float per array element, so every tile had no blades.
+`u_f4v` uploads arrays of `vec4`.

+**HDR10 output on the Vulkan renderer** — `r3d_hdr(on)` asks for an ST 2084 / BT.2020 swapchain where the
+display offers one.
+
+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 converts the interface to the same white; HDR metadata is set where the loader has
+the command. The screen and LDR images are 10-bit while it is on, and screenshots refuse rather than write
+a PQ image as SDR. OpenGL and the Vulkan SDR frame are unchanged. `R3D_HDR` overrides the setting.

+**Mesh-shader grass** — on a card with `VK_EXT_mesh_shader`, `r3d_mesh_grass(on)` draws each chunk of grass
+tiles as one mesh-shader dispatch, and a blade that is culled emits no vertices at all.

+- **`ludic-dev shaders`** — a variant whose first file is `*.mesh` compiles that stage as a Vulkan 1.3 mesh
+  shader; its SPIR-V keeps the `.vert` name, so the manifest is unchanged.
+- **The seam** — `gpu_has_mesh()` and `gpu_draw_mesh_tasks(x, y, z)`; a mesh program's pipeline has no
+  vertex input and its bindings the mesh stage. The device enables `meshShader` and `maintenance4`.

+**NVIDIA DLSS super resolution and Reflex on the Vulkan renderer** — through NVIDIA Streamline 2.14.1.
+
+- **The loader** — on Windows `Vk.open()` takes `sl.interposer.dll` beside the executable in place of
+  `vulkan-1.dll` when a program asks (`Vk.sl_prefer`), falling back to plain Vulkan without it; the `sl*`
+  exports and feature functions are reachable from Ludic.
+- **render3d** — `r3d_dlss(mode)` upscales the lit HDR frame before bloom and the tonemap, jittered on a
+  Halton cycle, with preset K in every mode (the default M cost 18 ms a frame at 4K on an RTX 3070 Ti);
+  `r3d_dlss_render_w/h` give the size to render at. `r3d_reflex(mode)` sleeps each frame and marks
+  simulation, submit and present. `R3D_DLSS`, `R3D_REFLEX`, `R3D_DLSS_PRESET`, `R3D_SL_LOG` for tests.
+- **Commands the interposer lacks** — it exports no `vkSetHdrMetadataEXT`, `vkCmdDrawMeshTasksEXT` or
+  acceleration-structure command; `Vk.has` checks one and `vkGetDeviceProcAddr` reaches it.
