<title>OG image template</title>
<!--
  Brand-consistent 1200x630 Open Graph image template, parameterized via the
  URL query string. Driven by `e2e/tools/og.spec.ts` (Playwright takes a
  full-viewport screenshot at exactly 1200x630).

  Query parameters:
    name   = tool display name        (e.g. "JWT Debugger")
    path   = URL path on tools host   (e.g. "/jwt")
    desc   = single-line description  (e.g. "Decode, verify, sign HMAC JWTs.")
    accent = hex color for accent bar (e.g. "%237b6ff7" -> "#7b6ff7"); default brand yellow
    icon   = symbolic id for the inline SVG icon (key | shield | cert | doc | bolt | id | grid)
    theme  = "dark" (default, brand) or "light"

  This file is local-only (no fonts loaded from the network -> deterministic
  screenshots; no network -> file:// works in CI sandboxes). System UI fonts.
