Previously the cycle validator rejected any link whose source had a
vector index >= target's, which silently killed legitimate connections
between nodes added in the wrong drop order.
Switch to a DFS over source_ids: an edge from->to creates a cycle iff
`from` already (transitively) depends on `to`. topo_sort runs after
each topology change so the vector ends up in a consistent order
regardless of how nodes were inserted.

Two bugs:
1. Dropped nodes were pushed to the end of the pipeline, but the Output
node already sat there from startup. The cycle validator and the
compiler only look for sources at indices strictly lower than the
target, so new nodes were invisible to the Output. Fix: insert
dropped nodes before the first Output; topo_sort also stable-moves
Output nodes to the back.
2. ColorEdit3 with default flags rendered RGB text inputs alongside the
swatch; clicking them dragged the node instead of opening the picker.
Fix: NoInputs + NoLabel leaves only the swatch (a single item), and
ed::Suspend/Resume wraps the call so the popup isn't clipped to the
node or captured by the canvas.

The previous InvisibleButton captured mouse events, so you could drag
from the Functions palette into the canvas, but node dragging and
slider interaction inside the canvas stopped working.
Fix: watch the global drag-drop payload without an explicit target. When
the mouse releases LMB over the DAG window with a "DAG_NODE_TYPE"
payload active, queue an add at that canvas position. No button, no
capture.
Tests (compiled standalone with preprocessor defines):
- dag_compile: 6/6 asserts (empty, single gen, op chain, multi-source
blend, Output-driven fragColor, unconnected-Output fallback).
- dag_catalog: 8/8 asserts (uniqueness, per-kind input invariants,
exactly one Output, body_glsl present & returns, control param
indices valid).
Build with:
g++ -std=c++17 -Icpp/functions -DDAG_COMPILE_TEST cpp/functions/gfx/dag_compile.cpp cpp/functions/gfx/dag_catalog.cpp -o /tmp/dag_compile_test
g++ -std=c++17 -Icpp/functions -DDAG_CATALOG_TEST cpp/functions/gfx/dag_catalog.cpp -o /tmp/dag_catalog_test

Previously SetNodePosition was called after EndNode every frame, which
reset any drag the user had done. Now the initial position is set once
per editor_uid (tracked in a static unordered_set), and the editor owns
the position afterwards. GetNodePosition at end-of-frame keeps step
state in sync for future persistence.

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.

Nuevo primitivo compartido:
- cpp/functions/viz/plot_static.h: header-only con flags ImPlotFlags /
ImPlotAxisFlags agrupados (NoFrame|NoMenus|NoBoxSelect|NoMouseText +
Lock|NoInitialFit|NoHighlight) para visualizacion estatica en
dashboards. Lo usan todos los charts de viz/.
Charts refactorizados a v1.1 con parametro `height` explicito (rompe el
feedback loop con contenedores AutoResizeY que producia vibracion al
redimensionar) y ejes pineados con ImPlotCond_Always:
- bar_chart v1.2: tooltip al hover (label + valor) + auto-rotacion de
labels a 45 cuando no caben horizontalmente (medidos con CalcTextSize
vs ancho del plot). Los labels rotados se dibujan manualmente con
ImDrawList::PrimQuadUV + ImFontBaked::FindGlyph (API ImGui 1.92+).
- pie_chart v1.1: tooltip por slice (detecta cual via atan2 desde centro
en sentido CCW matematico, que es como ImPlot dibuja los slices desde
angle0=90) con label + valor + porcentaje. Aspect 1:1 mantenido.
- line_plot, scatter_plot, histogram v1.1: ejes pineados con limites
calculados de min/max + 5% headroom (histogram usa AutoFit por los
bins dinamicos, con Lock para bloquear pan/zoom).
kpi_card v1.2: card mas compacta — altura 78px (antes 108), font scale
1.4x (antes 1.8x), padding sm (antes md). Apto para densidades altas
de KPIs en dashboards.
fullscreen_window v0.2: NoScrollbar|NoScrollWithMouse para eliminar el
scrollbar fugaz que aparecia cuando el contenido excedia por 1-2px la
ventana, reflow de ancho y vibracion visible al redimensionar.

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.

ImGui native BeginDragDropSource/Target over each CollapsingHeader.
Drag source adjusted if ahead of target to keep final position correct.
Move Up/Down buttons kept for keyboard/touchpad fallback.

kpi_card:
- v1.1: envuelve el contenido en BeginChild con surface bg + border +
radius::md + padding::md (tokens). Replica Mantine Paper withBorder
radius="md" p="md" usado en @fn_library/kpi_card.tsx.
- Ancho adaptativo via GetContentRegionAvail — requiere contenedor que
propague ancho constrained (ImGui::BeginTable). dashboard_grid / BeginGroup
no funcionan porque no constrainen ancho y la card desborda la celda.
- Linea de trend SIEMPRE visible: delta, sparkline, o em dash (text_dim)
como placeholder, para que un grid de KPIs quede alineado vertical.
- Colores del delta via tokens (success/error) en vez de hardcoded ImVec4.
bar_chart:
- v1.1: altura explicita como parametro (default 200px). Sin esto, ImPlot
con ImVec2(-1, 0) entra en feedback loop cuando esta dentro de un
dashboard_panel (BeginChild con AutoResizeY): plot pide espacio -> padre
se redimensiona -> plot recalcula. Efecto visual: las barras se deslizan
los primeros frames.
- Ejes blindados: Lock + NoInitialFit + Cond_Always ademas de los flags
previos. Y max pre-calculado con 15% de headroom.
- Sin inputs (NoInputs|NoFrame|NoBoxSelect|NoMouseText): estos charts son
de resumen, no de exploracion.
Actualizados los .md correspondientes con el contrato visual + requisitos
de contenedor, para que cualquier dashboard que componga estos primitivos
obtenga el mismo look.

- cpp/functions/gfx/gl_loader.{h,cpp,md}: mini loader para OpenGL 2.0+
(Linux no-op via GL_GLEXT_PROTOTYPES, Windows wglGetProcAddress)
- Portar gl_shader/gl_framebuffer/fullscreen_quad/shader_canvas al loader
- CMakeLists: WIN32_EXECUTABLE para lanzar sin consola en Windows
- apps/shaders_lab/shaders_lab.exe: binario PE32+ precompilado

Trasladar principios del DESIGN_SYSTEM.md de @fn_library (Mantine/React)
al mundo C++/ImGui sin añadir deps externas:
cpp/functions/core/
tokens — colors/spacing/radius/font_size como constexpr +
apply_dark_theme() al ImGuiStyle global. Dark + indigo
primary (Mantine-inspired).
badge — etiqueta inline 6 variantes (Default/Success/Warning/
Error/Info/Outline). <Badge> de @fn_library en C++.
empty_state — placeholder centrado para tablas/listas vacías.
page_header — header con title + subtitle + separator + hueco
para acciones (patrón begin/end).
Scope limitado (KISS) a fases 1-2 del plan: tokens + 3 primitivos.
No se duplica dashboard_panel con un "card" — el existente ya cumple
el rol. Fases 3-5 (charts ImPlot line/area, app_shell con navbar,
toast/alert) quedan fuera hasta que el dashboard crezca en alcance.
Resultado:
- 869 funciones (+4) en registry.db.
- Dashboard con header homogéneo y empty states en todas las tablas.
- Sin hardcode de ImVec4 disperso en views.cpp.
Diary + CHANGELOG actualizados.
