Some checks failed
When an application has no icon attached, render a deterministic monogram SVG instead of the generic picture-frame placeholder. Initials are picked from capital letters in the name (ShelfLife -> SL); fall back to the first two letters when fewer than two capitals exist (Audiobookshelf -> AU). Background colour is hashed from the name for stable per-app identity across visits. Adds an optional second icon attachment, icon_dark, alongside the main icon. When present, render a <picture> with a prefers-color-scheme: dark source so the browser swaps automatically; when absent, the main icon is used in both modes. The SVG sanitization, content-type fix, and size/format validation now run over both attachments uniformly. Bumps to 0.14.0. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
