Marketing landing: full WorkClaw-structure clone with ship-crew copy

Rebuilt the public landing to mirror WorkClaw's complete section layout
(verified against tools/wc-capture/out/shots/marketing.png), with original
"clawmates crew on a ship" copy and captured WorkClaw art wired as
swappable placeholders.

Sections (top to bottom): sticky pill nav (dark Get-started CTA) · hero
(dual CTA + trust row + crew banner) · crew strip · positioning headline +
four trait badges · One-click setup (periwinkle panel) · Works where you do
· Always on watch (dark panel) · Your work, your way (3 skill tiles) ·
Safety built into the hull (security columns) · FAQ on the blue field · Build
your AI crew CTA on the dotted field · dark footer.

- No SOC 2 / compliance claims (p7-marketing enforces this); honesty kept by
  replacing WorkClaw's customer-logo marquee with our own crew strip.
- A11y: AA contrast fixes — text-xl coral CTAs (large-text bar), darker
  coral-strong accent on periwinkle, deeper FAQ blue for white text.
- New tokens: marketing-blue, marketing-coral-strong.
- visual.spec marketing test scrolls + waits for lazy art before the shot;
  regenerated the marketing baseline. (Deepest <img> — the security art —
  renders for users but is blank only in Playwright's full-page capture.)
- Vendored the captured WorkClaw asset bundle under public/images/.

Built, typechecked, linted, p7-marketing + @visual green, deployed via
Compose and verified live on :3000.
