<!-- "default", not "black-translucent", now that there are two themes.
black-translucent draws the clock and battery in white and lets the page run under
them; on a light page that is white on near-white, and the meta is read once at
launch so no script can correct it. With "default" iOS tints the status bar from
<meta name="theme-color"> below and picks the glyph colour to contrast with it, so
it follows the theme on its own. The trade is that the page no longer extends under
the bar, which makes env(safe-area-inset-top) 0 in standalone — src/styles/pwa.css
already derives --sb-safe-top from that env(), so it collapses to 0 and the header
sits where it does in a browser tab. -->

<!-- Theme colors.
Two tags with media queries, which is how the browser answers before any script has
run and how a client with no JavaScript answers permanently. They are the page's
own ground (--sb-bg in src/styles/theme.css), not the brand orange: this paints the
Android address bar and the iOS status bar, and a strip in a different colour from
the page reads as a rendering fault rather than as branding.
Once theme-boot.js runs it drops the media attributes and writes the resolved
colour into both, because a media query cannot express "light on a dark system",
which is exactly what someone who picked a theme by hand has asked for. -->

preserves it exactly. There used to be eight separate <link> tags here and at
the end of <body>: 21 KB of CSS in total, but eight round trips before the
browser could paint, which GTmetrix measured at 441 ms on a throttled mobile
connection. Bytes were never the problem; requests were. -->

<p class="sb-pre-eyebrow">Чим ми вирізняємось</p>
<h2>Чому SecureBit - особливий</h2>
<ul class="sb-pre-grid">
<li class="sb-pre-card">
<h3>Багатошарове ядро шифрування</h3>
<p>Обмін ключами ECDH P-384, корисне навантаження в AES-256-GCM, підписи ECDSA і повна валідація ASN.1 - зведені в один загартований конвеєр.</p>
<ul class="sb-pre-tags"><li>ECDH P-384</li><li>AES-256-GCM</li><li>ECDSA</li><li>ASN.1</li></ul>
</li>
<li class="sb-pre-card">
<h3>Чистий P2P через WebRTC</h3>
<p>Повідомлення йдуть напряму між пристроями через WebRTC. Жоден relay не тримає ваших даних - сервер лише допомагає двом учасникам знайти одне одного.</p>
<ul class="sb-pre-tags"><li>DTLS 1.3</li><li>Без relay</li></ul>
</li>
<li class="sb-pre-card">
<h3>Досконала пряма секретність</h3>
<p>Сеансові ключі змінюються безперервно й відкидаються після використання, тож один скомпрометований ключ ніколи не відкриє попередніх розмов.</p>
<ul class="sb-pre-tags"><li>Ефемерні ключі</li><li>Автоматична зміна</li></ul>
</li>
<li class="sb-pre-card">
<h3>Маскування трафіку</h3>
<p>Розміри пакетів і паузи між ними доповнюються та рандомізуються, тож метадані не складаються в помітний візерунок навіть для того, хто стежить за каналом.</p>
<ul class="sb-pre-tags"><li>Доповнення пакетів</li><li>Розкид у часі</li></ul>
</li>
<li class="sb-pre-card">
<h3>Жодного збору даних</h3>
<p>Без облікових записів, без журналів, без збереження повідомлень. На сервері немає нічого, що можна злити, вилучити за ухвалою чи продати.</p>
<ul class="sb-pre-tags"><li>Без облікових записів</li><li>Без журналів</li></ul>
