KatanA Desktop

🚀 Features - Interactive HTML viewer: Local files and HTTP/HTTPS documents now open inside KatanA with CSS, JavaScript, same-origin resources and iframes, links, text input, and pointer or keyboard interaction. ✨ Improvements - Browser-compatible layouts: HTML slide decks preserve viewport-based sizing, multi-column and flex layouts, gradients, fixed controls, explicit line breaks, multilingual text, centered number badges, and paging controls. - Responsive HTML interaction: High-rate pointer and scroll input no longer blocks discrete clicks, keyboard input, navigation, or later frame updates, and the avoidable delay before the first HTML frame has been removed. - Actionable HTML errors: On-screen diagnostics now identify the failed operation and document with the root cause, including HTTP status, server verification challenges, and JavaScript runtime failures. 🐛 Bug Fixes - Document switching: A completed request for an older remote URL can no longer replace a local HTML document opened afterward, and interactions no longer reuse a stale frame from the previous document. - Local HTML URLs and slideshows: Opening a file:// URL now preserves its query and fragment, loads same-folder iframe content, advances interactive slides, and shows a specific in-page error when an iframe file is missing instead of leaving a blank preview. - Image viewing controls: Fullscreen zoom remains active while panning in every direction, and image controls keep a fixed high-contrast background and border on light themes and white images.
