Adds a `brandBody` helper in setup/lib/theme.ts that wraps prose in
brand cyan (#2BB7CE), with the same TTY/NO_COLOR/truecolor gating used
by `brand`/`brandBold`/`brandChip`. The helper splits multi-line input
and colors each line independently so the SGR sequence doesn't bleed
across clack's gutter prefix.
Routing:
- `note()` (the un-dim card wrapper from #2095) now passes
`brandBody` as its `format` callback, so card bodies render
cyan line-by-line.
- Every prose `p.log.{message,info,success,step,warn}` call in the
setup flow wraps its body argument in `brandBody`. Calls whose
body is explicitly `k.dim(...)` (failure transcript tails, log
paths, claude-assist response previews) are left alone — those
are the "preview/debug" cases the dim-policy comment in
theme.ts already carves out.
- Spinner-finish lines in windowed-runner / claude-assist color
only the message portion; the `(5s)` elapsed suffix stays dim.
Brand cyan accents (chips, wordmark, inline emphasis) are unchanged.
This PR only adds the body color.
A follow-up will add OSC 11 dark/light detection so light-mode
terminals get a brand blue (#2b6fdc) variant — opt-in upgrade with
no regression for the dark-mode default.
Clack's `p.note` defaults to `format: e => styleText("dim", e)`, which
fades note bodies regardless of the project's stated readability stance
(see comment on `dimWrap` in setup/lib/theme.ts: "prose renders at the
terminal's regular weight"). The dim styling makes body copy hard to
read on dark terminals and visibly washes out brand-colored segments
embedded in cards (e.g. the chip + bold heading rows).
Add a `note()` helper in setup/lib/theme.ts that wraps `p.note` with a
pass-through formatter, and route every setup-flow `p.note` call site
through it: setup/auto.ts, every setup/channels/*.ts adapter, and the
two setup/lib/claude-* helpers.
Pre-styled segments (brandBold, brandChip, formatPairingCard,
formatCodeCard) now render at full strength instead of being faded
alongside surrounding prose.
