/* Terazi — uygulama kabugu: yerlesim, sol menu, ust bant, icerik alani
 *
 * Gorsel yon (2026-09-14): giris ekraninin dili iceri tasindi.
 *   · Sol menu her temada koyu "murekkep" zemin; tonu temanin vurgusundan
 *     turer (koyu/acik → lacivert, nane → yesil, bugday → kahve). Uygulamanin
 *     kimligi burada durur. Is ekranlari (icerik) temanin kendi yuzeyinde,
 *     okunakli ve sade kalir — acik temalarda koyu menu + acik icerik bilincli.
 *   · Masaustunde menu sayfa kayarken yerinde durur; ust bant da oyle, arkasi buzlu.
 *   · Aktif menu ogesi: vurgu tonlu zemin + terazi renginde isikli kenar cizgisi.
 *   · Sayfa basligindaki nokta, "terazi" yazisindaki isikli i noktasinin yankisi.
 *   · Hareket kisa ve anlamli: sekme degisince icerik hafifce yukselir.
 *
 * Renk/olcek belirtecleri 01-token.css'ten (uretilir, elle duzenlenmez).
 * Asagidaki tureyen degiskenler o belirteclerden hesaplanir; giris ekrani da
 * (05-sayfa.css) ayni degiskenleri kullanir.
