/* Kalus shared styles.
   Direction: lean and centered (after celigo.com): light page, plain text tabs with dropdowns,
   centered section headings with one-line subheads, one primary action per block.
   Brand colors kept from the original kalus.io: forest green, lime, cream.
   Progressive extras: view transitions, scroll-driven progress, scroll-state header, anchor positioning, @property. */
