/* Stone Bridge Capital — brand stylesheet.
 *
 * Re-expressed from the brand's own delivered site (a compiled React/Tailwind
 * bundle; this repo has no build step and the application runs on the shared
 * vanilla engine). Its vocabulary, kept distinct from the other brands here:
 *
 *   - DARK. Every marketing band is deep navy (#0d2238 / #0a1b2d / #0e2238),
 *     separated by a 1px sky-950 rule; text is white and slate. The only light
 *     surface is the application card, which sits white on navy.
 *   - SQUARE. No border radius anywhere — buttons, inputs, cards, options.
 *     Lavor is rounded and light; do not converge them.
 *   - SKY-300 (#7dd3fc) micro-caps eyebrows are the only accent colour; the
 *     primary button is white with near-black text, inverted on the form.
 *   - Plus Jakarta Sans at 600 for headings (not 800), a serif wordmark.
 *   - A narrow 1024px column throughout.
