CodeMirror measures text per character; Fira Code's ligature glyphs
render wider than the measured sum of their parts, corrupting cursor
and selection rendering. The font is set on .cm-content with ligatures
off, and inner spans inherit it for consistent metrics.
FastAPI backend rendering HTML with html5tagger, content persisted in a
kanta database and rendered per request. Vue only for the editing tools
(page editor over a WebSocket, site/structure editor); public pages are
plain HTML with fetch navigation. No auth: single trusted author.
