Minor release. An opt-in accent stripe for callouts, a readable line-length measure for prose, a refined intent treatment on KPI tiles and stage cards, and refreshed marketing-blueprint copy — all backward-compatible.

Added

<x-wirekit::callout> gains an opt-in stripe prop. It adds a one-sided accent bar and is off by default (the plain callout is the alert-style tinted border). Pass stripe to bring the bar back.
<x-wirekit::prose> gains a measure prop — a readable line-length clamp. Long-form text caps at a comfortable ~65 characters per line by default; use measure="wide" (~78ch) for a roomier column or measure="none" for the full container width. Themeable via the new --measure-wk token.

Changed

<x-wirekit::callout> no longer shows the accent stripe by default. The plain callout is now the balanced tinted border; add the new stripe prop to restore the one-sided bar.
<x-wirekit::stat> and <x-wirekit::stage-card> intent treatment is now a balanced 4-sided tinted border (previously a one-sided left bar). The intent color cue is unchanged — only the shape is refined.
<x-wirekit::prose> now clamps long-form text to a readable measure by default. Existing prose wraps at ~65ch; set measure="none" to restore the previous full-container-width behavior.
