What

The home/session banner drew the codev wordmark in the active theme's secondary (teal in dark, purple in light) with a tint-derived drop shadow, so the TUI and the marketing site showed the same glyph art in different colors. This recolors it to the landing page's brand palette. The glyph art itself is unchanged.

	before	after
banner, dark	teal #0891b2 + shadow	co theme foreground, dev brand red #ee0033
banner, light	purple #7b5bb6 + shadow	co brand navy #19224c, dev brand red
CLI banner (--help, upgrade, web, uninstall)	bold teal + shadow	bold, no shadow, co default fg, dev brand red
--mini C badge	teal / purple	brand red, both modes

Reference: codev-landing-page app/components/PixelWordmark.tsx (text-brand-navy dark:text-foreground + text-brand-red) and app/globals.css (--color-brand-navy, --color-brand-red).

Notes

• wordmarkHalves keeps each row split into its "co" / "dev" halves so each takes its own color; wordmark (plain lines) is composed from it. The component now paints one bold <text> per half instead of per-char shadow cells.
• The --mini badge color was not a guess: codev-landing-page app/icon.svg renders the same compact "C" glyph in #ee0033 in both modes. Because it is mode-independent, splashTheme drops the forked pick param and returns to upstream's (theme, indexed) signature — so this PR is a net reduction in divergence for that file.
• Deliberately fixed brand colors rather than a theme token: this is a brand wordmark, and the landing page has no shadow behind it.

Verification

• bun typecheck clean in packages/tui and packages/opencode.
• packages/tui: 244 pass / 0 fail. packages/opencode/test/cli/run: 196 pass / 0 fail (theme.test.ts mark assertion updated to [238, 0, 51]).
• Driven in tmux at the real home screen; captured escape codes:
  • dark — co = 238;238;238 (theme foreground), dev = 238;0;51
  • light — co = 25;34;76 (#19224c), dev = 238;0;51
  • --mini entry badge — 238;0;51
• The --mini exit badge draws from the same mark_fg = input.theme.mark binding in the other branch of build, so it follows by construction; it is confirmed by code path, not visually, because showExit requires a session with history and the scratch run had none.

DIVERGENCES.md rows for logo.ts, component/logo.tsx, cli/ui.ts, run/splash.ts, and run/theme.ts are updated, plus a CHANGELOG.md Unreleased entry.
