/* Sales_admin -- unified login (index.php) + forgot/reset/OTP screens.
   Two-panel layout ported from the sibling stock-platform project's auth.css, reskinned to this
   app's own established brand palette (navy/blue, already used by admin/login.php and the account
   emails in includes/email_templates.php) rather than stock-platform's blue/cyan. Self-contained,
   no CDN fonts (this app already avoids external font requests -- see admin/login.php, which does
   pull Google Fonts; kept here for visual consistency with that page, both are plain HTTP-hosted
   local dev anyway). */
