/* Sirius Peptides product site (siriuspeptides.com).
   Independent of public/styles.css and of campaign.css.
   Clinical: navy/teal, Newsreader hero, pill buttons, card grids.
   Campaign: warm ink/copper, split waitlist, sharp stacked Inter display.
   Product: cool mist, olive, horizon masthead, sticky index, hex lockup.

   Contrast trap (do not regress): do NOT set heading/link colour on `body.prod h*`
   or `body.prod a`. Those beat every dark-panel override (footer, chapter-dark)
   and paint ink/olive onto forest. Base colour lives in :where() so section
   rules can win. AA: normal text >= 4.5:1, large text >= 3:1. Lime is
   decorative / large-on-dark only. */
