El modal Save-as-generator usaba BeginPopupModal + InputText + Button
crudo. Ahora usa fn_ui::modal_dialog_begin/end + fn_ui::text_input +
fn_ui::button del registry. El error inline usa fn_tokens::colors::error
en vez de ImVec4(1, 0.4, 0.4, 1). Anade modal_dialog.cpp, text_input.cpp
y button.cpp al CMakeLists del app.
Raw ImGui::Begin*/Selectable/BeginPopupModal: 11 -> 8.
Sustituye ~30 lineas de cableado manual de save/load/list/delete contra
layout_storage_sqlite por dos llamadas a la nueva API publica:
g_layouts = fn_ui::layout_storage_open("shaders_lab.db");
fn_ui::layout_storage_make_callbacks(g_layouts, g_layout_cb);
El blob pendiente lo gestiona el storage (layout_storage_apply_pending).
on_reset se override para ademas re-mostrar los paneles de shaders_lab.
La tabla ui_layouts heredada queda intacta — la nueva API usa
imgui_layouts en la misma BD.
Wave 1 de parallel-fix-issues integrada a master:
- 0025: text_editor_cpp_core + file_watcher_cpp_core
- 0026: gl_texture_load_cpp_gfx (vendor: stb_image v2.30)
Ademas se commitea WIP previo de master que estaba sin commitear (cambios
en shaders_lab, dag_*, framework, tokens, kpi_card, gl_loader.md, etc.)
para dejar HEAD buildable.
Notas:
- Algunos deps del gallery (button.cpp, toolbar.cpp, modal_dialog.cpp...)
siguen UNTRACKED — gating con FN_BUILD_GALLERY=ON (default OFF) para
que master build (sin flag) no los necesite.
- Build OK con y sin flag. fn index registra 904 functions.

- DagStep: preview_open flag (default false).
- dag_compile: emit `uniform int u_preview_target` and a series of
early-return branches at the start of fragColor selection. -1 (default)
falls through to the real Output-driven fragColor.
- dag_node_previews (new fn): per-node FBO keyed by editor_uid, lazy
created. Renders each node with preview_open=true to its FBO by
setting u_preview_target = step index. Texture exposed via
dag_preview_texture(uid) for ImGui::Image.
- dag_node_editor: small toggle button "[+] preview"/"[-] preview" in
each non-Output node; when open, ImGui::Image(96x64, V-flipped).
- dag_node_editor: double right-click on hovered node deletes it
(Output is protected).
- main.cpp: dag_previews_render after Canvas DAG; dag_previews_destroy
on shutdown.
Single GL program drives both the canvas and all thumbnails — moving
sliders never recompiles, only the topology change does.

Canvas Code and Canvas DAG are now independent windows, each with its
own ShaderCanvas, FBO and compiled program. Both render every frame in
parallel. No more focus-based recompile — each source compiles when its
own content changes.

Remove Code/DAG toggle. Each panel lives in its own dockable window.
Active source (Code or DAG) is whichever window has focus; Canvas title
shows the current active source. Switching active source triggers an
immediate recompile so the canvas reflects the selected pipeline.
