Nitro's orange accent selection fill clashed with accent-colored text.
Introduce --selection-bg (base: accent 30% mix, as before) used by both
::selection and the editors' selection layer; nitro overrides it with a
neutral grey. CodeMirror's selection needed a baseTheme with its exact
&light/&dark selectors to win, and is now hidden when unfocused like a
normal input.
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.
