//! Arkham Intel adapter — pure-HTTP client for `api.arkm.com`.
//!
//! Auth contract (verified 2026-04-30 against live api.arkm.com):
//! - `X-Timestamp: <unix epoch seconds>`
//! - `X-Payload:   sha256(KEY + ":" + sha256(path + ":" + ts + ":" + KEY))`
//! - `Origin: https://intel.arkm.com` (CORS-pinned by server)
//!
//! `KEY` is the build-time `NEXT_PUBLIC_WEBAPP_CLIENT_KEY` baked into the
//! SPA's JS bundle. Same value for every user — there is no per-user secret
//! for the public data surface (~75 of 84 documented endpoints). The
//! ~9 user-bound endpoints (`/user`, `/user/portfolio`, `/turnkey/wallet`,
//! `/user/alerts*`, etc.) return `null` / `[]` without an additional auth
//! cookie that the SPA sends via `withCredentials:true`.
//!
//! Server enforces a < 18-minute replay window on `X-Timestamp`.
//!
//! No browser, no Cloudflare bypass, no cookies needed for the data surface.
