/**
 * Reusable dark-themed HTML email template.
 *
 * Email clients have limited CSS support, so everything is inlined and layout
 * uses tables for Outlook compatibility. The design mirrors the app's dark UI:
 * near-black card on neutral background, Inter typography with safe fallbacks.
 *
 * Default is monochrome (white CTA on dark). Pass `brandColor` to tint the
 * CTA button and inline links — Clips, for example, passes its purple.
 *
 * Usage:
 *   const { html, text } = renderEmail({
 *     preheader: "…",
 *     heading: "You're invited to join Acme",
 *     paragraphs: ["Alice invited you to join…"],
 *     cta: { label: "Accept invite", url: "https://…" },
 *     footer: "If you weren't expecting this, ignore this email.",
 *   });
