/* A SMALL DESIGN SYSTEM, NOT A FRAMEWORK.
 *
 * The page has one job and one screen: decrypt a file, sync a wallet, send a transfer. A theme with
 * hundreds of components would be bigger than the page itself, and every component it does not use is
 * a class name nobody can explain later. What is here is the whole visual language: tokens, a column,
 * cards, fields, buttons and a log.
 *
 * COLOURS COME FROM THE BRAND: near-black background, soft grey text, one warm accent used only for
 * the action the person is meant to take. Status colours (ok, warn, bad) are separate from the accent
 * on purpose: an accent-coloured refusal would read as a suggestion.
 *
 * NO EXTERNAL FONT, NO EXTERNAL STYLESHEET: the page is served with `script-src 'self'` and
 * `style-src 'self'`, and a font from a CDN would be both a network dependency and a privacy leak.
 * The stack resolves to the platform's UI font (Inter where it is installed).
