v1.2.0

30 July 2026

• Add three accessible components: Sheet for portalled edge panels, snippet-driven Tabs with automatic/manual activation and Accordion with single/multiple expansion
• Add file_drop attachment with accept filtering, directory expansion and explicit drop errors
• Add hover/focus triggers and open/close delays to Popover
• Add rich snippet bodies and validated ask_prompt() requests to the queued dialog API
• Extract headless theme helpers (apply_theme_mode, resolve_theme_mode, system_preference, shared theme state) to svelte-widgets/theme, so CommandMenu / PageSearch actions can set the theme without duplicating ThemeToggle's localStorage + data-theme logic, and the toggle icon stays in sync
• Add svelte-widgets/katex with katex_preprocess(), a before/after preprocessor pair that hides rendered KaTeX behind collision-safe placeholders around mdsvex so markdown cannot mangle the math HTML
• Drive draggable / resizable with pointer events (pointerId filtering, pointercancel, setPointerCapture) so touch works and a gesture over an iframe or stolen focus still ends cleanly; resize hit-testing is now edge strips that cover the border box
• Harden dismiss_on: 'release': ignore clicks whose primary press started inside, and add backdrop_dismiss for modal ::backdrop vs padding. Wire dismiss_on through MultiSelect / Popover / DraggablePane (pane defaults to release, plus an element-only inside prop)
• Add FullscreenButton placement="corner" and optional per-page icons on SubpageGrid
• Make text search match NFC/NFD-equivalent Unicode and skip hidden form-control text
• Breaking: Unify build-time heading IDs, runtime heading anchors and Toc on the same Unicode-preserving slugger and collision allocator, and make heading parsing tolerate > inside quoted attributes while ignoring comments and code/script/style containers. This changes generated IDs containing punctuation or non-ASCII text and changes duplicate suffixes from the old Toc slugger
• Document every headless subpath and attachment, including the lower-level backdrop and outside-press dismissal primitives
