+# Hedge sample library manifest
+
+`hedge-sample-library.svg` is a review-only, hand-editable SVG source. It is
+not a web, firmware, or generated LittleFS asset.
+
+## Symbols
+
+- Intact straight variants: `hedge-intact-1` through `hedge-intact-6`.
+- Topology examples: `hedge-base`, `hedge-corner`, `hedge-crossing`, and
+  `hedge-end`.
+- Perseverance frames: `hedge-impact-1` through `hedge-impact-4` and
+  `hedge-breakthrough`.
+- Permanent openings: `hedge-breach-1` through `hedge-breach-3`.
+- Reusable primitives: `leaf-cluster-a`, `leaf-cluster-b`, and `twig-fork`.
+
+All edge art is authored left-to-right. Later integration may rotate it by 90,
+180, or 270 degrees and mirror it only when the shared-edge centre remains
+aligned. Highlights are distributed rather than directional, so rotation does
+not create a lighting contradiction.
+
+## Accessibility and review
+
+The dark outline, branch forks, irregular leaf silhouette, and clear central
+gap distinguish the symbols without relying only on hue. The comparison sheet
+contains neutral and dark-cell previews at 34, 40, and 46 CSS-pixel targets.
+Impact frames are static review frames; no animation, particle system, or
+runtime event is implied.
+
+## Size and dependency record
+
+| Source | Raw bytes | gzip -9 bytes | Dependencies |
+| --- | ---: | ---: | --- |
+| `hedge-sample-library.svg` | 6,495 | 1,884 | None; inline SVG only |
+
+The validator rejects scripts, raster payloads, external URLs, editor metadata,
+and missing stable identifiers. Reused `<use>` primitives avoid duplicating
+leaf and twig paths. The current sheet is deliberately outside the 1.5 MiB
+runtime budget until a future approved integration milestone selects a family.
