The assistant rules file documented a 70/30 split and
`--dai-dock-width: max(340px, 30vw)`. The code now reads
`clamp(320px, 20vw, 460px)`, so the doc was describing a layout that no
longer exists — and it is an instruction file, so a stale value there
gets implemented rather than questioned.
Records the three width regimes, the 900px overlay behaviour, that the
floor means 1024px renders at 31% and not 20%, and that DOCK_NORMAL in
AIPanel.jsx must stay byte-identical or the page jumps on first paint.
Also notes in the src/lib/assistant/ copy that it is a duplicate and that
its DoormileAI.css is dead — nothing imports it.
