/* FINDEUS — public site and sign-in.
 *
 * The dashboard is an instrument panel: dense, monospaced, every pixel doing
 * work. This is the opposite surface and follows the opposite rules — space,
 * scale, and one idea per screen.
 *
 * The reference is Apple's marketing pages, which is a specific and testable
 * thing rather than a vibe:
 *
 *   - Type does the work. Very large display weights (600, not 700) with tight
 *     negative tracking, set against generous line height at body size. No
 *     decorative fonts, no letterspaced small caps as ornament.
 *   - Two surfaces per theme, alternating. Light is #fff / #f5f5f7; dark is
 *     #000 / #0a0a0a. Sections switch between them so structure comes from
 *     value, not from borders.
 *   - Depth is translucency and blur, never drop shadows pretending to be
 *     elevation. The nav is frosted glass over content that scrolls beneath it.
 *   - Radii are large and consistent (18–28px) and buttons are full pills.
 *   - Motion is a single easing curve, always decelerating, always short.
 *     Nothing bounces. Nothing spins.
 *   - Colour is almost absent. One blue for action; green and red are reserved
 *     for money and appear nowhere on this page.
 *
 * Dark is the default because the app is, and a white flash on the way to a
 * black dashboard is the cheapest possible way to feel unfinished.
