/*
* yearn.css — a classless stylesheet with a soft, playful, browser-company feel.
*
* Usage:
*
* optional theme, loaded after
*
* Write plain semantic HTML. Optional knobs (attributes, not classes):
* force a mode (default: follows the OS)
*
* hero gradient (also works on any element)
*
*
* Conventions:
* body > header inset gradient hero (nav + h1 + p + buttons)
* body > footer inset dark card
* a[role=button] link styled as a button
* button ~ button later siblings render as secondary buttons
* section > article + article becomes a responsive card grid
* form[role=search] single-line pill search bar
* input[role=switch] toggle switch
* h5 / h6, hgroup > p:first-child mono "eyebrow" labels
