   STREAM RV — SOLAR & LITHIUM UPGRADES  ·  route: /service/solar-lithium
   wrapper: .srv-power. The shop's signature specialty — part service page,
   part showcase. Dark hero (the only sub-page that gets one — earned, it's
   the flagship), then cream. All styles scoped under .srv-power, tokens on
   the wrapper (NOT :root), no global resets, no header/footer.
   DEV: owner to approve copy — composed from approved fragments + FAQ voice.
   DEV: form is a visual shell only — inject the working form at implementation.
