/* Chenet Login Page Styles
   Light look of alexanderchenet.com (Mag. Alexander Chenet, "Copilot für Leader:innen"): white
   surfaces, text #222326, website gold #9a7d36 (wordmark, top band) with the darker gold #80652a for
   the button and #5f4b1f / #463816 for hover and links, warm light greys #fbfaf8 / #f5f3ef / #e4e0d8.
   No external fonts (the website uses Plus Jakarta Sans and Newsreader from Google Fonts; they are
   only named here and used when installed locally).
   Logo: /css/chenet/logo_full.png (gold "Alexander Chenet" in Newsreader, gold rule and the claim
   "COPILOT FÜR LEADER:INNEN", transparent, 738 x 138 px, shown at most 369 px wide) replaces the
   app's login logo via content: url() and sits on a white band with a gold top edge like the
   website's gold top bar. All colours are fixed so the page looks the same whatever theme is
   selected. */
