0.3.0

Added

• \.responsiveLayout environment value: the canonically resolved layout
  family as a value (override → scene truth → container size class → phone),
  for feeding computed properties, view arguments, and pure functions without
  the closure APIs. \.containerResponsiveLayout is the container-shaped
  companion that deliberately ignores scene truth.
• responsiveContentWidth(tabletFraction:): caps scroll content to a readable
  fraction of the scene width on tablet layouts (default
  baseTabletLayoutRatio), full-width on phone — the SwiftUI analogue of
  UIKit's readableContentGuide. Applied to a ScrollView's content, the
  scroll surface stays edge-to-edge.
• accessibilityScrollFloor(_:): declares a compressible floor for greedy
  views (aspect-ratio images, maps) inside accessibilityScrollView(_:), so
  they shrink to the floor before the scrolling decision fires instead of
  forcing permanent scrolling via their large ideal height.
• sceneLayout(mocking:) + SceneLayoutMockValues: publish a synthetic scene
  environment for previews and tests, making every scene-truth read — family, size,
  orientation, safe area — resolve against declared values on any canvas.
• SceneLayoutEnvironment.isLandscapeAspectRatio: whether the scene is wider
  than tall — the aspect-ratio answer layout math wants, distinct from
  interfaceOrientation under freely resized windows.
• SceneLayoutReader is now public: closure-based scene-truth access with
  self-discovery when no anchor exists upstream.
• DocC article "First Frame and Scene Discovery": the sceneLayout == nil
  first-frame contract and the prescribed one-expression fallback patterns.
• Demo app coverage for the new APIs: resolved-value readouts, a readable
  content width screen, a compressible-floor screen, and a mocked-scene
  preview.

Changed

• Claude Code skill (responsivelayoutkit) documents the new value-level,
  content-width, floor, mock, and reader APIs, and warns against hand-rolled
  resolution chains. Plugin bumped to 1.1.0.
