The design distinguishes apps by stylized brand glyphs (Notion N,
YouTube ▶, Dribbble dot, X 𝕏, Vercel ▲, Behance Bē, Figma F,
Slack #, GitHub ◯, Linear L, plus reading and news clusters). Add
chrome::brand_glyph with a host → Brand dispatcher so any place that
shows an app icon can route through one helper instead of inventing
fallback initials.
Wire it into the home favorites tile first — tabs whose host matches a
known brand now show the proper glyph; unknown hosts still get the
gradient initial fallback. Tests cover canonical hosts, www/subdomain
normalization, the news/reading clusters, and unknown rejection.
