Subject: [PATCH] ui: redesign brand icon and fix clipped wordmark
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- new mark: measurement-span glyph on rounded brand-gradient badge
  (favicon, inline logo, standalone tmflow-logo.svg)
- wordmark moved from SVG <text> with hardcoded x offsets (clipped
  "Flow" past the 260px viewBox, font-dependent overlap) to plain HTML
  spans — never clips, natural kerning, theme-adaptive
- _app_logo.html params: logo_class, wordmark_class, logo_id (unique
  gradient id when logo appears twice per page)
