TextShadow for Text, TextEntry, and Container

Added GooTokenScope for defining reusable tokens directly in the inspector.

Supports color, length, float, integer, boolean, string, and texture tokens.

Text rich mode through new Text(content, true) or IsRich = true

Markdown support for emphasis, strong text, strikethrough, links, headings, lists, quotes, inline and fenced code, and line breaks, while preserving engine-supported inline HTML

Generic mounted text-file loading through Text.Path; file extensions do not select plain or rich rendering

Skins.NineSlice(string path, ...) with lazy mounted-file loading, path caching, and retries after failed loads

Virtualization: Virtual blob (Virtual.List/Grid/Custom factories) over the engine's BaseVirtualPanel

GooVirtualList: fiber-backed list rows with panel recycling. Persistent fiber per row, pooled panels, rediff on item change

GooVirtualGrid: same recycle machinery (extracted into abstract GooVirtualPanel) plus engine GridLayout math

State<T> + Track<T>( initial ) on both GooPanel and Cell. Auto-dirtying state for mutation outside event handlers (timers, network, polls): writing a different Value marks the owner dirty, no manual Rebuild()

Each.Of( items, builder ) / Each.Of( items, keyOf, builder ) plus a Children.Add overload for it: keyed list building inline in a Children = { ... } initializer instead of a separate AddRange call

Children.Add( in T? child ): nullable-child overload, the conditional-child idiom that replaces AddIf

Layout.Stack() and Layout.Layer( child ) with overloads for Container, Sector, Arc, and Polygon

Hud.ScrollArea, Hud.DismissScrim, Hud.FillRect: factories for the three most common test case patterns (bounded-height scroll triple, invisible dismiss click-catcher, absolute left-anchored fill bar)

Controls.Slider optional palette params: trackColor, fillColor, thumbColor

Viewport.CenterOn( world, screenPoint ): pin a world position to a given screen point

Perf: opt-in live pipeline profiler (Perf.Enabled, Report(), Reset())

Native reactive UI particles via Hud.Particles / ParticleField

GPU SDF arbitrary-polygon shapes (points-texture packing), plus a stable-identity AddRange overload for keyed lists Position/offsets, PointerEvents and BorderRadius exposed on Scene, Svg and Web panels

Controls.Popover(open, trigger, content, anchor, onDismiss, gap, key) helper for controlled anchored popover (Top / Bottom / Left / Right / BelowStart) with click-away light-dismiss - adjacent to the engine's Sandbox.UI.Popup and BasePopup

Goo.PointerDrag - frame-polled move/resize drag

Container.SwallowClick - fixes click-bubbling

Container.Disabled - Pointer off and reduced opacity

LayoutTransition - GlideState -- unified animation state system

expanded Image blob - positioning, Border, Radius, ImageRendering

Text.Style, UniformValue.Time, motion token

Cell.Mount - replaces hand-rolling _seeded guards

damper Tick(dt) - all 9 damper types now have Tick delta time

KeyTracker.Pressed rising-edge query

ShaderEffect refactor: construct from a shader path with an indexer uniform bag.

Uniforms accept per-frame functions and a built-in clock:

Hud.Overlay() - full-screen HUD root column layout, pointer-through (does not swallow game input)

Hud.Fill() - absolute layer, pointer-through; the standard Hud for shader effects

Hud.Scrim(color) - edge-pinned tinted backdrop for modals. PointerEvents left to the caller so it can toggle on open/close

Hud.Wallpaper(texture, path) - background image layer by texture or by path

Hud.Anchored(anchor, content, padding) - pins content to a screen corner or edge center, pointer-through

Hud.Spacer() - flex-grow gap that pushes siblings apart

Hud.Divider(color) - 1px full-width horizontal rule. low-alpha white by default.

Controls.Button(...) ready-made button and Children.AddIf(condition, child)

Container.Disabled forces pointer-off and dims, per node, applied after state variants.

Container.SwallowClick stops a click from bubbling

PointerDrag frame-polled move/resize helper, UI-scale correct via Current(panel)

PaddingX/Y

MarginX/Y

BorderTopRadius

BorderBottomRadius

BorderLeftRadius

BorderRightRadius

All 9 animation dampers gain Tick(dt).

KeyTracker.Pressed(name) rising-edge query.

Text.Style takes a TextStyle bundle for one-shot font blocks.

Cell.Mount<TCell>(key, seed, configure): seed runs once at first mount, configure every rebuild.

Image gains a positioning subset and defaults BackgroundRepeat to NoRepeat, stopping ObjectFit.Contain tiling

goo updated to 275570:

TextEntry primitive

TextEntry auto-grow default to 2.5x with override

TextEntry character limiting, regex matching behavior, character limits

Separate click routing for left/right/middle click

Scroll behavior implemented

Added a "viewport" primitive allowing for pan/zoom "infinite" canvases
