/* BoroughLets marketing site.
 *
 * One stylesheet, no framework, no build step. The content security policy on the
 * distribution forbids unsafe-inline, so every rule lives here: no <style> blocks
 * and no style="" attributes anywhere in the HTML.
 *
 * The palette is the product's own design tokens (frontend/src/styles/variables.css)
 * for light surfaces, and the demo film's gradient (compose.py) for dark ones. They
 * are one system: the film's ground is the app's primary blue pushed darker.
 *
 * Three contrast rules, measured rather than assumed:
 *   the brand green #5CB85C is 2.48:1 on white, so it is decoration on light
 *     surfaces and never text, and never a button fill with white text;
 *   the app's muted grey #7a7a8a is 4.22:1 on white, which fails AA for body text,
 *     so this site uses #5f5f70 (6.25:1);
 *   the app's focus ring colour is 1.12:1, so focus here is a solid 3px ring.
