/* ── Paywall (P3, iOS IAP) ───────────────────────────────────────────
   Lives here, beside the .upgrade-prompt-* family it reuses, because this file is
   always-loaded from index.html. A lazily-loaded fragment would leave the sheet
   unstyled until the user happened to open some other panel first.

   SMALL TEXT USES A DERIVED COLOR, NOT --text-secondary. That token is fine in four
   themes and fails in the fifth: in base Onyx it is #71717a on a #09090b sheet, 4.12:1,
   under the 4.5:1 AA threshold for normal-weight text — and the text affected included
   the App Store disclosures at 0.78rem, the text that least deserves to be hard to read.
   Mixing --text-primary toward --panel-bg keeps the visual hierarchy while deriving from
   each theme own tokens: 7.81:1 Onyx, 7.23 plum, 5.96 light, 6.19 graphite, 6.53 press.
   Pinned by tests/unit/paywall-contrast.test.mjs.
   Deliberately does NOT use --text-tertiary: that token has 7 uses and 0
   definitions repo-wide, so it resolves to its hardcoded fallback and no theme can
   override it. --text-secondary is real in all five themes.                       */
