# them, Tailwind stops using its built-in stock radius scale for .rounded-md
# etc and ALWAYS reads var(--radius-md) instead — everywhere in the app, not
# just inside the new assistant-ui components. WeLe's CallsPage.jsx already
# uses the bare `rounded-md` utility (confirmed by grep), so this would have
# silently grown its corner radius from Tailwind's stock 6px to shadcn's 8px.
# Scoping wouldn't fix it either: outside the scope var(--radius-md) would be
# UNDEFINED, and Tailwind falls back to `unset` (radius 0) rather than its own
# stock default once a theme key is declared at all. Removing these four lines
# is the only clean fix — Tailwind's stock scale then applies uniformly, and
# assistant-ui's own components just use that stock scale instead of shadcn's,
# a difference nobody will notice.

# ── 6. In @theme inline: stop forcing Geist as the global sans font. ─────────

# app-wide). WeLe already sets body { font-family: var(--font) } (Inter) as a
# plain, unlayered rule, which always wins over anything in a Tailwind layer
# per the CSS cascade-layers spec — so body content keeps using Inter either
# way. Removing this line just stops `font-sans` utility usage elsewhere from
# silently switching to Geist, and keeps the new AI Assistant UI visually
# consistent with the rest of the app instead of introducing a second typeface.
