Demo Mode screen — 6 curated scenarios, no auth required

[thefiredev-cloud]

Context

Split from #78 on 2026-04-23. Full Call Workflow server+UI shipped; Demo Mode was deferred because it has a different risk profile (hardcoded data, no LLM calls, no auth required).

Demo Mode lets a user — including an App Store reviewer, Christian, or a prospect from the landing page — see the app's value without signing up. Reduces friction + gives App Review a test path that doesn't depend on the demo account.

Scope — 6 curated scenarios

Each scenario renders a prebuilt search result (including Claude-generated narrative + citations) from a JSON fixture. No network calls, no auth, no Claude API usage.

Scenario	Query	Why
Cardiac Arrest	"adult cardiac arrest"	Highest-stakes protocol, shows ACLS citations
Pediatric Fever	"peds fever 6mo"	Shows weight-based dosing + Broselow
STEMI	"chest pain STEMI"	Shows destination logic + 12-lead acquisition
Refusal / AMA	"patient refusing care"	Shows documentation requirements
Trauma MVC	"trauma MVC high speed"	Shows transport tier + trauma center criteria
Stroke	"stroke LAMS positive"	Shows destination + hub-and-spoke logic

Files to create

• app/demo.tsx — route (public, no auth middleware)
• components/demo/DemoScenarioList.tsx — tile grid
• components/demo/DemoScenarioView.tsx — renders a saved scenario like a real search result
• data/demo-scenarios.json — 6 hardcoded fixtures with chunks + Claude-style response + citations
• Link from app/(landing)/ CTA or marketing site

Acceptance criteria

• /demo route renders without any auth token
• 6 scenario tiles, each navigates to the saved view
• Scenario view looks identical to a real search result (reuse existing ProtocolChunkCard, CitationChip, etc.)
• Footer disclaimer: "This is a demo. Always follow your agency's protocols."
• No tRPC calls from the demo screen — verify via network tab
• Added to Tools tab with "Demo Mode" card (no requiresPro, no featureFlag, always visible)
• Copy includes "Try it risk-free" and deep-links to signup CTA
• Analytics event fires on scenario open (if user later signs up we can attribute)

Out of scope

• Real Claude inference (use fixtures)
• Save-scenario-for-later UX
• Demo mode for Tools tab agents (separate issue if needed)
• A/B testing of demo copy
