You are working on a **@lightningtv/solid** application. This framework renders to a **WebGL/Canvas GPU scene graph**, NOT the browser DOM. Applying standard web patterns will break things silently.
entries/Announcer loading property defers speech until all elements in the focus path are loaded.mdentries/Announcer singleton announces newly focused elements by diffing the focus path against previous state.mdentries/Announcer speak method supports append and notification modes for programmatic speech control.mdentries/Column component is a vertical navigable list with flexDirection column and 30px gap.mdentries/Config singleton holds all runtime Lightning configuration.mdentries/Config.focusStateKey controls which state string marks focused elements.mdentries/Config.fontWeightAlias maps named weights to numeric values.mdentries/Config.stateOrder controls style resolution priority when multiple states are active.mdentries/DOM renderer AnimationController interpolates numeric props using requestAnimationFrame.mdentries/DOM renderer defers image loading until node enters bounds using renderState tracking.mdentries/DOMNode renders Lightning visual properties as computed inline CSS on a div element.mdentries/DOMText measures its own dimensions after render to feed back into flex layout.mdentries/DefaultKeyHoldMap adds hold-key detection for EnterHold.mdentries/DefaultKeyMap defines the six standard TV navigation keys.mdentries/Effects interface provides eight shader effects applicable to element nodes.mdentries/ElementNode animate method requires rendered state and returns a chainable IAnimationController.mdentries/ElementNode chain and start methods enable sequenced animation queuing.mdentries/ElementNode emit method bubbles custom events up the parent chain.mdentries/ElementNode is the primary abstraction for all renderable elements in Lightning TV Solid.mdentries/ElementNode lng property holds a plain object before render and the live renderer node after.mdYou are working on a @lightningtv/solid application.

notes/guardrails.md (in this skill's directory)entries/index.md (in this skill's directory)The entries/ directory contains a wiki-linked knowledge graph. Start from the guides:
| Guide | Domain |
|---|---|
entries/core guide.md | ElementNode, renderer, config, task scheduling |
entries/styling guide.md | Flex layout, states, transitions, shaders/effects |
entries/focus guide.md | Focus manager, key handling, capture/bubble phases |
entries/navigation guide.md | Row/Column nav, spatial nav, scrolling modes |
entries/components guide.md | Row, Column, Grid, Virtual, Image, Lazy, and more |
entries/input guide.md | useFocusManager, useHold, useMouse, key maps |
entries/accessibility guide.md | Announcer, speech synthesis, ARIA labels |
entries/performance guide.md | Virtual scrolling, lazy loading, preserve, task queue |
entries/routing guide.md | HashRouter, KeepAlive, route preservation |
Each entry is titled as a prose statement (e.g., "Row component is a horizontal navigable list with built-in flex layout and 30px gap") and contains YAML frontmatter with type (api/pattern/gotcha/architecture/comparison) and module fields.
