/* Assistant frame — owns its own styling so every tenant gets the same rhythm
   as the host workflow: a 16px gutter (--space-4), 22px page titles, 14px muted
   helper text, cards inset 12px like every other list in the app. Colors and
   spacing come from core tokens (public/app/app.css), so tenant accents apply. */

/* Shared component idioms (rtb-btn, rtb-row, rtb-field, rtb-empty, ...).
   agents.js renders these class names, but their styles ship with the rtb
   pack, so tenants without it (homebuilder, Lifestyle) got unstyled pages.
   These are verbatim copies of packs/rtb/public/rtb-base.css, scoped with a
   zero-specificity :where() to the content area while it hosts the agent
   sub-nav. Each copy has the same specificity and values as its original and
   keeps the original order, so on RTB (where rtb-base.css also loads) the
   computed result is unchanged; this block sits before the agent-specific
   rules below so those still win as before. Keep in sync with rtb-base.css. */
