/*
 * Styles for the Rails-rendered surface: sign-in, magic link, the second
 * factor, password reset, connected accounts, /account. Every page that uses
 * `layouts/application.html.erb`, and nothing else.
 *
 * SCOPE — read this before adding a selector.
 *
 * Two other layouts render HTML in this app and **neither loads this file**:
 * Administrate's /ops pulls `Administrate::Engine.stylesheets` only, and
 * MissionControl's /ops/jobs pulls Bulma plus its own. That is what makes the
 * bare element selectors below safe. It is also a thing to check rather than
 * assume if either gem is upgraded: the moment one of those layouts includes
 * `application.css`, a global `input`/`table`/`body` rule here restyles a
 * console that was already styled.
 *
 * NO BUILD STEP. Propshaft serves this verbatim — no Sass, no autoprefixer, no
 * `@import` resolution. Plain CSS only. Native nesting is deliberately avoided
 * so the file stays greppable by selector.
 *
 * The palette is shadcn's neutral scale, matching `frontend-nepal/src/app/
 * globals.css` — same near-black primary, same 0.625rem radius. Copied rather
 * than shared because there is no pipeline between the two, so it will drift;
 * that is an acceptable price for pages a traveller sees for about fifteen
 * seconds between clicking a link and landing back on the site.
