 * DGR Web v12 "Ember" — iç sayfaların ortak yüzey dili (projeler · hizmetler · süreç · iletişim · örnek site · yasal · SSS).
 * Yalnız token kullanır (theme.css). core'un .card/.card--glow/.u-mark sözleşmesiyle aynı görünüm; önek .pg- (çakışma yok).
 *  - .pg-card         : yüzey + 1px çizgi + üst iç ışık + 16px köşe
 *  - .pg-card--glow   : gradyan kenarlık (turuncu → şeffaf, 1px maske) + ince imleçte yükselme ve turuncu gölge
 *  - [data-pg-spot]   : imleci izleyen ışık (pages.js --mx/--my/--spot yazar)
 *  - .pg-head         : bölüm başlığı (eyebrow + h2 + intro) · .pg-mark: tek vurgulu kelime + el çizimi dalga
 *  - .pg-list         : onay işaretli sade liste · .pg-num: mono sıra numarası · .pg-ico: 44px ikon kutusu
 * Hareket: yalnız transform/opacity. off/reduced'da her şey statik ve görünür.
