/* DESIGN ROLL
   Concept: root system
   Layout: asymmetric two-zone (large brand taproot block + branching link map)
   Top edge: layered hills (SVG)
   Surface: gradient soil strata (Field Guide family herb/lavender/kraft)
   Newsletter: "plant your email" button with sprout feedback on submit
   Extras: month-aware growing-season tips strip · shipping/guarantee trust badges · inline SVG payment icons · back-to-top rising sprout
   Signature: taproot SVG connects link branches; season tip rotates by calendar month; newsletter sprout grows on plant
   Nav family match: shares --fg-* herb/lavender/kraft/bark from Field Guide Deck — different layout from Developer Pool lily pads / Almanac split / 4-col gray
