/* =========================================================================
   dimadeev.de — Shared design system
   One source of truth for every dashboard/public page: tokens, type,
   the panel/tile/badge/button/form vocabulary, icons, motion.

   Loaded via <link rel="stylesheet" href="/assets/sidebar.css"> AFTER each
   page's own (legacy, now mostly redundant) inline <style> block — later
   same-specificity rules win the cascade, so this file's tokens and
   components already take over even before a page's local CSS is trimmed.

   Component naming: .panel is canonical. .term / .term-bar / .term-body
   (used by settings.php, login.php, the login popup) are the exact same
   component under an older name — aliased here rather than renamed in
   every file, so nothing breaks by not being touched yet.
