root-at-skicandClaude Opus 5.5 22815a9940 Archify Diagram Viewer 0.1.0
VS Code extension that previews Archify diagrams from their JSON sources
(live, as you type) and opens rendered Archify HTML in a viewer tab.
Bundles the Archify 3.0.1 renderer and runs it on VS Code's Node runtime.
Adds validation diagnostics, JSON schema help, source-link navigation,
export saving, render-to-file and open-in-browser commands.

// Unicode 16.0 reclassified the trigrams (U+2630-U+2637) and the monogram /
// digram symbols (U+268A-U+268F) from Neutral to Wide, so both are in; and
// Hangul Jamo Extended-A stops at U+A97C, its last assigned jamo, because
// U+A97D-U+A97F are unassigned, and unassigned code points outside the CJK
// ranges UAX #11 names default to Neutral rather than Wide. Spelled out as
// ranges because V8 has no \p{East_Asian_Width=W} property escape.
