What

• README hero — the root, dsh-mneme/ and mcp/ READMEs now open with images/mneme-banner-hero.webp (1672×941, 282 KiB). The 2.1 MiB source PNG would have doubled the images/ directory. The root README uses a relative path; the two sub-READMEs use the raw absolute URL because npm does not resolve relative image paths (../images/... breaks on npmjs.com).
• Plugin-list icon — package.json's icon now points at assets/icon.png (256×256 RGBA, rounded corners genuinely transparent, 120,715 B — under the host's 256 KiB cap). The retired assets/icon.svg is removed; docs/DIRECTORIES.md and CHANGELOG.md follow.

Tests

• The icon case in test/client.test.js no longer compares the SVG against the inlined MNEME_MARK_D (the list icon and the sidebar mark are intentionally different marks now). It validates the PNG itself: magic bytes, 256×256 IHDR, 8-bit, colour type 6 (RGBA) — the host falls back to a generic glyph on a bad file without reporting an error.
• Mutation-checked: 512×512 → red, RGB without alpha → red, restored → green.
• Full suite: 3446 tests, 3445 pass, 0 fail, 1 skipped.
