The earlier safe-area fix reached the bottom bars (they apply --tg-safe-bottom) but not the header: its top inset lived only in a Telegram-fullscreen-scoped rule, so on the native build the header .bar had just 5px top padding and its content sat under the status bar (measured: the title at y=11px behind the 54px bar; the back button untappable). Give .bar a top inset from the SystemBars plugin's --safe-area-inset-top (native-only via the plugin var; unset -> 0 on web/PWA/Telegram/VK, so no regression; tg-fullscreen still overrides via specificity). Verified on-device (Pixel_10 / API 37): the title moved from y=11 to y=65, clear of the status bar.
