Redesign homepage around durable agent memory

[ccf]

Summary

• reposition the homepage around AgentCairn's core promise: one durable Markdown memory trail across coding agents
• replace the generic feature sequence with a real capture → canonical file → cited recall story
• add an agent-specific install chooser, explicit index-rebuild proof, clearer benchmark evidence, host automation tiers, and a stronger final conversion module
• regenerate the Open Graph card to match the new product story
• harden desktop, tablet, and mobile rendering, including exact command wrapping, accessible disclosure and chooser states, and zero page-level overflow
• isolate Playwright from Astro's development toolbar by testing the production static build on a dedicated port

Why

The previous page explained the implementation but did not establish a distinctive product category or guide each visitor toward the correct install path. The redesign makes the owned Markdown vault, replaceable index, and cross-agent continuity concrete while preserving the project's local-first and open-source character.

Validation

• npm run check — zero diagnostics
• npm run build — six static pages built
• npm test — 45/45 Playwright tests passed, including desktop/mobile Axe coverage
• visually verified in real Chromium at widths from 320px through 1440px
• git diff --check origin/main...HEAD
• repository pre-commit suite passed

Deployment

Cloudflare's Git integration should create an isolated preview for this PR. Production remains unchanged until this PR is merged.

Note

Low Risk
Static Astro site, marketing copy, and test config only—no runtime product or auth changes; regression risk is mainly visual/layout and E2E coverage.

Overview
Redesigns the marketing homepage around one durable Markdown memory trail across agents, instead of a generic feature stack and hero install commands.

The hero now leads with CTAs and a MemoryTrail vignette (remember → canonical file → cited recall), and drops the old HeroDiagram and inline plugin commands. Inversion becomes the “how it works” contract section with vault proof and three contract points; Differentiators, HowItWorks, ClaudeMemoryCallout, Quickstart, and TrustSecurity are removed from the page flow.

New InstallChooser (per-agent routes + otherInstallHosts) and FinalCTA (install command synced via agentcairn:install-change) replace scattered quickstart/trust blocks. Measured leads with plain-language takeaways and tucks full tables behind <details>; AgentsSupported shows ambient / sweep / explicit tiers with the full matrix in a disclosure. SurvivesUninstall is restyled with updated demo copy.

Content in content.ts is rewritten (nav anchors, hero, installPaths, messaging, theme color). OG image matches the blue-green trail story. CopyButton / CommandBox accept custom aria-labels; nav gets 44px hit targets and a Guides menu.

Playwright serves dist/ on port 4173 with reuseExistingServer: false so dev toolbar never pollutes tests; smoke, a11y, and reduced-motion specs are updated for the new IA.
