/*
 * Hercules Client Portal — the surface.
 *
 * `packages/ui/src/tokens.css` positions this front end as "the terminal, softened", and the
 * softening is the whole design brief. The back office is an INSTRUMENT: 13px, dense, a nav rail
 * of thirty-five routes, built for somebody who lives in it. This is a DOCUMENT, read once by
 * somebody who has never seen it, on a phone, deciding whether to trust a broker with their
 * money. So:
 *
 *   type      15px base and a 1.55 line height, against the console's 13/1.45. Body text a
 *             stranger reads carefully is not the same as a column a professional scans.
 *   width     a 560px measure on forms and 900px on the hub. A field that spans a 27-inch monitor
 *             is a field nobody can see the label and the input of at the same time.
 *   radius    12px, against the console's 6 and the dealing terminal's 0. Rounding costs density
 *             and buys approachability, and only one of those matters here.
 *   motion    present but short. A form that animates is a form that feels slow on the fourth
 *             screen; a step that slides in once tells you where you are.
 *
 * FOUR THINGS THIS STYLESHEET DOES THAT ARE NOT DECORATION:
 *
 *   1. NO INLINE STYLE, ANYWHERE. The CSP ships `style-src 'self'` with no `unsafe-inline`, which
 *      blocks the style ATTRIBUTE as well as the tag. A width written with `setAttribute('style',…)`
 *      renders at zero and says nothing. `el()` writes `node.style.cssText`, which is a CSSOM
 *      write governed by `script-src`, so it applies — but everything that can be a class is one.
 *   2. THE FOCUS RING IS NEVER REMOVED. `:focus-visible` is styled up, not away. This is a form
 *      somebody may be completing with a keyboard, a screen reader, or a phone's switch control,
 *      and the single most common accessibility defect in a sign-up flow is an invisible focus.
 *   3. TOUCH TARGETS ARE 44px MINIMUM. Every control, on every breakpoint. The console can put a
 *      24px icon button in a table row because it is used with a mouse; a client tapping "resend
 *      code" on a train cannot.
 *   4. ERRORS ARE NOT COLOUR ALONE. Every invalid field gets a border, an icon and a sentence.
 *      Roughly one man in twelve cannot reliably see the red.
 *
 * `prefers-reduced-motion` is honoured for real: the transitions are removed, not shortened.
