v0.5.0

[0.5.0] - 2026-03-23

Breaking changes

• Canvas group redesign. Interactive elements are now groups with
  top-level fields (id, on_click, a11y, etc.) instead of a nested
  "interactive" sub-object. Only groups can be interactive -- leaf
  shapes (rect, circle, etc.) are no longer interactive on their own.
• Standalone transform/clip commands removed. push_transform,
  pop_transform, translate, rotate, scale, push_clip,
  pop_clip are no longer supported as standalone shape types. Use the
  transforms array and clip field on groups instead.
• Group x/y fields removed. Use transforms: [{"type": "translate", "x": ..., "y": ...}] instead.
• Event families renamed. canvas_shape_* -> canvas_element_*,
  shape_id -> element_id in event data.

Added

• Transforms on groups. Groups carry an ordered transforms array
  (translate, rotate, scale) and an optional clip field, replacing
  standalone push/pop commands.
• Transform-aware hit testing. Full 2D affine matrix tracks
  translate, rotate, and scale through nested groups. Cursor positions
  are mapped to local space via the inverse matrix. Clip regions from
  ancestor groups are intersected and tested.
• Focus lifecycle events. New event families: canvas_element_blurred,
  canvas_focused, canvas_blurred, canvas_group_focused,
  canvas_group_blurred.
• Click-to-focus. Clicking an interactive element grants the canvas
  keyboard focus and sets internal focus to the clicked element.
• ID-based focus tracking. Focus survives element reordering between
  renders. Stale elements are detected and blurred automatically.
• Focus style. New focus_style field on groups for visual feedback
  when keyboard-focused. Priority: pressed > hover > focus.
• Suppressible focus ring. show_focus_ring: false disables the
  default ring (use focus_style for custom indicators).
• Geometry-aware focus rings. Ring shape adapts to hit region: rounded
  rectangle for rect, circle for circle, capsule for line. Full transform
  support via matrix decomposition.
• Arrow mode. New arrow_mode canvas prop: wrap (default), clamp,
  linear, none.
• Focusable groups. Groups with focusable: true become Tab stops
  for two-level navigation. Tab moves between top-level entries, arrows
  navigate within the focused group.
• Canvas accessible role. New role canvas prop (defaults to group
  when interactive, image otherwise). active_descendant set
  dynamically from focused element.
• Accessibility tree structure. Focusable groups create parent-child
  relationships via traverse(). Child accessible nodes have widget IDs
  for active_descendant resolution.
• Validation diagnostics. Warnings for: interactive elements without
  a11y, stateful roles missing state props (switch/toggled,
  radio/selected), elements without set position.
• focus_element widget op. Programmatically focus a canvas and set
  internal focus to a specific element.
• click_element / focus_element test interact actions.
• CanvasElementFocusChanged message. Single message for blur+focus
  transitions, split into separate outgoing events by the emitter.
• Theme-aware canvas colors. Color strings in fill, stroke, and text
  that match iced palette names ("primary", "text", "background",
  "success", "danger", "warning") are resolved against the current
  theme at draw time. Canvas shapes now participate in the theme system.
• Focus-visible pattern. Focus ring and focus_style only show for
  keyboard navigation (Tab), not mouse clicks. Matches iced's built-in
  button behavior.
• Custom focus ring radius. New focus_ring_radius field on groups
  for shape-matched focus rings (e.g. pill-shaped toggles).

Fixed

• WASM build: replaced wasm-opt --all-features with explicit feature
  flags for compatibility with older wasm-opt versions.
• Canvas style overrides (hover_style, pressed_style, focus_style) now
  correctly read from the group, not from children.
• Canvas keyboard events now work when the mouse cursor is outside the
  canvas bounds.
• Canvas focus visuals (focus ring, focus_style) clear when the canvas
  loses iced-level focus.
• text_editor cursor no longer resets on every keystroke. Content hash
  is updated after TextEditorAction to prevent stale prop sync.
• text_editor cursor movement, selection, and click-to-position now
  work. All actions (not just edits) are performed on the Content.

Changed

• Release binary assets renamed from plushie-{os}-{arch} to
  plushie-renderer-{os}-{arch}. WASM archive renamed from
  plushie-wasm.tar.gz to plushie-renderer-wasm.tar.gz.
• Updated to plushie-iced 0.8.0.
