/*
 * carnotif shared theme layer (decision #61 in docs/06-decisions.md).
 *
 * Tailwind's Play CDN (loaded in base.html) is still the primary styling
 * tool for one-off layout/spacing via utility classes in markup. This file
 * adds the small set of reusable *component* classes (buttons, cards,
 * badges, banners, form fields) that templates previously reinvented ad hoc
 * in every file. Keep it plain CSS: Play CDN only scans HTML for utility
 * classes, it does not process `@apply` in linked stylesheets, so no
 * Tailwind-specific syntax below.
 *
 * Radius convention: `.btn` / `.field-input` / `.badge` / `.banner`
 * ("controls") use 8px; `.card` ("containers") uses 12px.
