/* Light/dark theme for the free tools (CleanBites, ClearLab AI and its guides, Pill Identifier,
   Prescription Record). Loaded after each tool's own stylesheet by scripts/tools-theme.cjs.
   The tools share one base stylesheet, so the same tokens and fixes cover all of them.
   Printable sheets (medicine card, prescription record, pharmacist note) stay paper-white on purpose:
   they preview the PDF you save. Dark styles are screen-only, so printouts are always light. */
