Summary
Compresses the favicon from 164,673 bytes to 1,747 bytes by rebuilding it as a proper multi-resolution ICO with three PNG-compressed entries derived from the app logo, cutting a 16x site-loading asset.
Changes Included:
favicon.ico: Replaced the 9-entry uncompressed BMP ICO (164,673 bytes) with a 3-entry PNG-compressed ICO at 16x16, 32x32, and 48x48, derived from public/Logo.svg with transparency and generated locally (headless Chrome render + systematic downscaling + PNG-in-ICO container) without adding dependencies.
Apple touch icon note: The roadmap's second commit (apple-touch-icon) is already satisfied by PR 20, which shipped the 180x180 file, so this PR is intentionally a single commit.
