/* MoneyTrack dashboard — minimal typographic UI.
   Everything lives in this file on purpose: the CSP in auth.php sets
   style-src 'self', so inline <style> blocks and style="" attributes are
   blocked. default-src 'self' rules out webfonts and data: background images
   too, so this leans on system fonts and CSS-drawn shapes only. */
