/**
 * Public demo environment — the keyless fallback.
 *
 * When the MCP boots with no API key and no metrics backend, it attaches
 * READ-ONLY to the public 10x demo dataset instead of falling to POC mode.
 * This makes the keyless `npx -y log10x-mcp` first-run land on the same
 * orientation (log10x_start) and the same data as the website's live demo,
 * so the marketing promise ("demo mode, on the same dataset as the console")
 * is literally true.
 *
 * These credentials are PUBLIC read credentials: the same key/env ship in
 * the website's client-side config (console config.js) and authenticate the
 * hosted demo. Baking them here adds no exposure beyond what any visitor's
 * browser already holds. Mutating/account tools are denylisted in this mode
 * (see DEMO_FALLBACK_DENYLIST) so an agent cannot reconfigure the shared
 * demo account; sign-in tools stay registered as the upgrade path.
 *
 * Escape hatch: LOG10X_DEMO_FALLBACK=off boots straight to POC mode.
