Lotus CIandClaude Opus 5
e9a59336c7
- lotusTransparent without lotusTheme warns and applies the theme anyway; name tags/header/footer get a subtle text-shadow + backdrop blur under body.lotus-transparent (#21). - Landscape filmstrip shrink requires (pointer: coarse) so a short desktop/PiP window isn't reflowed as a phone (#32). - lotusParam re-reads window.location on every call (#33). Fixes #21 Fixes #32 Fixes #33 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PPmy3tPq869XDW4njjVaKA
