Scope:

Unified text compositor pass with collision classes and priority tiers.
Reserve fixed zones for legend + annotations.
Enforce min separation for pin labels around dense symbols.
Ensure orphan/floating labels cannot be rendered without visible anchor context.

Acceptance:

No overlapping pin/net labels in baseline fixtures.
Legend and annotation blocks never overlap schematic content.
Bus/net labels stay near relevant trunks/junctions.

Progress push cc20c0c landed.

Renderer improvements:

Added per-side pin label spacing resolver to reduce local pin text collisions.
Added separate per-side net-label spacing pass for per-pin net labels.
Moved annotation text into a dedicated annotation panel layer.
Legend now repositions below annotation panel.
Expanded blocked regions so net label placement avoids annotation/legend zones.

Validation:

npm test passing
npm run test:ui passing (baselines updated)

Follow-up readability patch f0b952e:

Net labels now include route-centered candidate anchors (representativePoint) before pin-anchor fallback.
Reduces 'floating label' artifacts where labels appeared detached from visible routed segments.

Regression status remains green (npm test, npm run test:ui).

Completed by 1a9c7b5 + prior label-placement commits (cc20c0c, f0b952e).

Delivered:

Dedicated annotation panel with blocked collision region.
Legend placement below annotation panel.
Pin/net label spacing resolver and blocked-zone-aware label picking.
Net label anchors prefer routed representative points to avoid floating labels.
Annotation word-wrap/dynamic width to prevent text spill into schematic canvas.

Validation:

npm test
npm run test:ui
Render regression hash updated and deterministic.

Marking done against acceptance criteria for non-overlapping baseline text layers.
