   Linear görünümü — "midnight precision instrument"

   Operatör, 21 Eki 2026: "paneli tamamen yeni bir tasarıma geçirmek
   istiyorum" (Linear'ın stil referansı, DESIGN.md + CSS değişkenleri) ve
   "sunucu performansıyla alakalı sorun yaratacaksa yapmayalım".

   style-v2 → style-beta → style-next üstüne yüklenir; yalnızca üst
   şeritte "Linear"ı seçen kişide (çerez tg_look=linear). Düzen "Yeni"
   görünümünkiyle aynıdır, burada yalnızca renk, yazı, çizgi ve köşe var:
   sayfaların HTML'i, formları ve betikleri değişmez.

   Kurallar style-next ile aynı: bulanıklık, @keyframes, dışarıdan dosya,
   uzun geçiş yok; gölge yerine ince çizgi. Bu dosya url( içermez.

   Referanstan panele uyarlananlar:
     zemin    Void #08090a · kart Carbon #0f1011 · yükseltilmiş Obsidian #161718
     çizgi    Graphite #23252a · güçlü çizgi Smoke #383b3f
     yazı     Paper #fff başlık · Mist #d0d6e0 gövde · Fog #8a8f98 ikincil
              (Ash #62666d koyu kartta 3.4:1 — okunurluk için ikincil metinde
              Fog'a yakın #7c818a kullanılır, AA)
     vurgu    Mavi #3565d9 (koyu) / #2f62d6 (açık) — yalnızca birincil eylem
              (Kaydet/.success), etkin menü/sekme işareti ve odak halkası.
              Referanstaki Acid Lime #e4f222 21 Eki 2026'da kaldırıldı
              (operatör: "sarı renk yerine mavi renk olsun, çok parlak sarı
              neon kötü kalıyor hem beyaz hem de koyu modda"). Düğme
              dolgusunda beyaz yazı 5.2:1 / 5.5:1, koyu kartta vurgu yazısı
              #7aa5ff 7.8:1.
     yazı tipi Inter (variable), ağırlık 400/510/590 — 700 yok
     köşe     kart 12 · düğme/alan 6 · rozet 4 · hap 9999
   Referans bir pazarlama sitesini anlatıyor (16px gövde, 96px bölüm
   arası); panel yoğun bir uygulama olduğu için gövde 14px, boşluklar
   "Yeni"deki gibi kaldı.
