Key Engineering Decisions
§1In-browser dynamic rendering over server-side images
By loading subsetted WOFF2 fonts on demand and drawing previews with the browser's native text engine, server CPU load is zero and user latency is instantaneous.
§2Glyph subsetting for lightning preview
Preview fonts are subsetted to the basic ASCII and Latin-1 supplement ranges (saving up to 85% of font payload size) until full download is requested.
Engineering Implementation Breakdown
// frontend
Interactive preview workbench with live text synchronization and size controls.
// backend
