• Birdsong is about a third as frequent.
• The night crickets are replaced by a far owl that hoots three times in a 24 second loop.
• Autumn trees' leaf accents shade toward the tree's own darker orange, not toward blossom pink.
• Trees no longer lean or rock, and their bark stays still. Only the leaf cards shiver.

Summary

Summary by CodeRabbit

• New Features
  • Wildlife ambience now features owl calls at night instead of crickets.
• Improvements
  • Leaf movement is refined, with less bending and shaking near the trunk.
  • Autumn foliage uses deeper accent colors.
• Documentation
  • Updated wildlife and nighttime sound descriptions to reflect owls.

The wildlife sound category now uses an owl instead of crickets, and its ambience synthesizer generates owl hoots. The leaf sway shader uses UV coordinates to keep zero-UV vertices still. The autumn accent blends the autumn color with the autumn shade.

Changes: Wildlife audio

Layer / File(s)	Summary
Owl category and ambience selection crates/hamlet_realm/src/sound/kinds.rs, crates/hamlet_realm/src/sound/mix.rs, crates/hamlet_realm/src/sound.rs, crates/hamlet_app/src/screens/settings.rs, docs/sound.md	The wildlife sound category replaces Crickets with Owl. The dark-period ambience selects Sound::Owl. Related setting, sound, and documentation descriptions now refer to owls.
Owl ambience synthesis crates/hamlet_realm/src/sound/synth/ambience.rs	The synthesizer replaces the cricket loop with a 24-second owl loop containing three randomized hoot groups. Bird events now use longer randomized intervals.

Leaf sway

Layer / File(s)	Summary
UV-aware sway and shader calls crates/hamlet_vfx/src/leaves_sway.wesl, crates/hamlet_vfx/src/leaves.wesl, crates/hamlet_vfx/src/leaves_prepass.wesl	swayed now accepts UV coordinates and leaves vertices with UV (0, 0) stationary. Other vertices receive shaking without bending. Both shader call paths pass UV coordinates.

Autumn accent

Layer / File(s)	Summary
Autumn accent blend crates/hamlet_realm/src/generator/flora.rs	The AUTUMN accent now blends pal.autumn with pal.autumn_shade. Its documentation describes the autumn accent as deeper.

Full details: Docstring Coverage

Explanation

Docstring coverage is 75.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 8 functions across 6 files. (4 skipped: 4 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

_{I hop through leaves where still trunks stand,
An owl calls softly across the land.
The birds take longer pauses in the air,
Autumn deepens its colors with care.
I tuck my ears and listen at night,
Then bound home beneath the moonlight.}

Review comments at @crates/hamlet_vfx/src/leaves.wesl:
- Line 53: Handle meshes without UV channel A in both leaf shader passes by
conditionally using vertex.uv when VERTEX_UVS_A is enabled and zero UV
otherwise. Update the swayed calls in the main leaves shader and leaves_prepass
shader to use the selected UV value, preserving their existing pass-specific
logic.
