/**
 * Template Style Model
 *
 * Super-Admin-managed "marketing style" templates (e.g. Russell Brunson,
 * Alex Hormozi, Neil Patel …). Each template captures a marketing STRATEGY
 * ONLY — conversion framework, page flow, content structure, messaging
 * approach, and CTA strategy — that the Landing Page builder can apply.
 *
 * Templates deliberately carry NO visual styling (colours, fonts, buttons,
 * radii, animation). All branding and visual design comes from the company's
 * own brand assets and visual identity.
 *
 * Templates are global (not company-scoped). Only enabled templates are exposed
 * to the Landing Page builder.
