Website tagline

The tagline is the short line under the logo. Someone who sees only the logo and that line should know what the business is there for. Positioning (website-positioning, POSITIONING.md) decides what the site claims; this skill finds the few words that carry it, together with the owner. Optional, never part of the default build.

The governing rule: the tagline says nothing POSITIONING.md does not already say. On any conflict, positioning wins and the tagline is rewritten.

The work has four moves, in this order: lead with purpose (§2), show six to eight variations (§3), ask the owner for a direction (§4), ask for feedback and refine until one line is picked (§5). The owner decides at every step; the assistant proposes.

Explain it first (what to say to the owner)
