/**
 * tg-shell.css
 *
 * Shared design tokens + layout primitives for /design/tg/ — every page in the
 * TG Mini App mockup tree links this stylesheet. Brand colour is BLUE only
 * (#1e40af → #3b82f6 gradient); no purple, green, or orange accents.
 *
 * Layout shape per page:
 *   ┌─────────────────────────────┐
 *   │ ☰  Page title               │  ← .tg-header (sticky, 56px)
 *   ├─────────────────────────────┤
 *   │  Scrollable content          │  ← <main>, padding 16px
 *   └─────────────────────────────┘
 *   [ TG MainButton (native) ]      ← Telegram chrome (per-page text)
 *
 * Hamburger drawer (.tg-drawer) opens from the left with a backdrop.
 * Width target: 390-430px (iPhone 12-15 Pro). Cards collapse to 1 column.
