/* ==========================================================================
   marketing.css - the PUBLIC (logged-out) shell.
   ==========================================================================

   Why this file exists
   --------------------
   The portal theme (portal-theme.css) is scoped to `html[data-portal="app"]`,
   which only views/loggedin/header.pug stamps. Public pages never get it, so
   every `--app-*` token is undefined there and a bare `var(--app-...)` is
   invalid at computed-value time. views/login.pug, views/register.pug and
   views/error.pug were left on the pre-portal Bootstrap shell for exactly that
   reason and ended up white-on-blue while the rest of the product went dark.

   index.pug, pricing.pug and docs/api.pug each solved it by inlining the same
   ~60 lines of CSS in a <style> block. This file is that same design language
   extracted once so the auth pages can share it instead of forking it a fourth
   and fifth time. The tokens below are copied verbatim from index.pug so the
   homepage -> login -> register funnel is one continuous surface.

   Deliberately NOT scoped to a data attribute and deliberately does NOT load
   Bootstrap: these pages own their whole surface. Do not add `var(--app-*)`
   here - those tokens do not exist on a public page.

   Loaded on its own (NOT via style.css) so none of the legacy leakage in
   style.css - `.btn { width: 100% }`, `nav { background: white }`,
   `.login-container`, `* { font-family: Roboto }` - can reach these pages.
