/**
 * Landing page styles for DikeBot.
 *
 * Theme approach: JS in the template forces data-bs-theme="light" on <html>,
 * so all CSS variables from _variables.css resolve to their light-mode values
 * automatically. No need to duplicate or override tokens here.
 *
 * Layout approach: The template sets {% block container_class %} to empty,
 * removing Bootstrap's .container wrapper. Hero is therefore full-width by
 * default. Content sections self-constrain via max-width.
 *
 * Neumorphic rule: panels/cards are RAISED (--shadow-e1 / --shadow-e2).
 * Inset is reserved for form inputs only.
