Three inline style="..." attributes were pure styling with no per-request
data behind them (a hero-block spacing tweak, a trailing note's margin, a
gap between two stacked rows) — moved each into dashboard.css as a scoped
structural selector so future adjustments happen in one place instead of
being split between the template and the stylesheet.
Also bumped .stream-title/.stream-user/.stream-icon in the Now Playing
card one step up the existing --fs-* scale (13px->15px, 12px->13px,
15px->18px) rather than introducing a one-off size.
Documented the "styles belong in CSS, not inline" rule in CLAUDE.md,
with the actual exception: per-request computed values (a meter's width,
a threshold colour) and JS-toggled initial visibility still can't live
in a static stylesheet and are fine to stay inline.
