Ark 0.5.3 — glass confirmation cards

Page confirmations now appear at the active page’s top-right in a translucent card with a subtle comic-burst silhouette.

• Native frosted glass, a fine outline and restrained system typography.
• A quick 280 ms pop with a small overshoot, followed by a quiet fade. Reduce Motion skips the pop; Reduce Transparency restores the material’s full opacity.
• The same Page copied and Hard refreshing… commands work in the main page, either focused Split pane, Peek and Little Ark.
• Narrow panes keep the complete message; repeated commands replace the previous confirmation without stealing focus or blocking clicks.

All seven component and five packaged runtime suites passed, including 207 browsing-feature checks covering placement, narrow panes, interruption and replacement. The installed app passed strict signature verification and matches the tested executable. Native checks confirmed both shortcuts show the complete card at the page’s top-right and dismiss cleanly. All 12 existing tabs and the original page/Space were retained. Broader theme checks and frame-by-frame animation timing remain unmeasured.

Apple Silicon, macOS 14+. Locally signed, not notarized. Ark remains an independent prototype; this release does not claim full Arc or Yab parity.
