/* =====================================================================================
   gs-site.css — the ONE stylesheet of GenAI Studio's signed-out website: the React
   landing page and sign-in view (src/landing/) and the static pages (/privacy/,
   /terms/, /support/). Skill: genai-all-web-marketing-site.

   It is linked from public/index.html, so it loads for SIGNED-IN users too. That is
   why it is fully namespaced:
     - every selector starts with .gs-site (the landing root, the auth view root, the
       splash root, or <body class="gs-site"> on a static page);
     - every class is gs-*, every custom property --gs-*, every keyframe gs-*;
     - no element selector, :root token or @font-face reaches outside .gs-site.
   The app's own global CSS still reaches in (Create React App bundles every
   stylesheet globally): `* {font-family: Roboto}` (GenAIApp.css),
   `form {position: fixed; bottom: 0}` (Practice.css, Homework.css), .textinput and
   .signonpagebutton (Signin.css, Practice.css, Homework.css), and the bundle loads
   AFTER this file. So the overrides below are deliberate and a little more specific.

   Owner UI rules: light theme only (no dark palette, no dark-scheme query); no
   pop-ups, overlays or toasts; no hamburger; every clickable control has a press
   cue (scale .96 + dim, dim only under reduced motion); 40 px+ tap targets; 16 px
   gutters; no horizontal page scroll at 320 px.

   - Top and bottom: the browser's 8px body margin. A negative margin cannot undo it,

     clipping box. So while the signed-out site is on screen, Signin.js puts
     .gs-site-body on <body> (a layout effect, removed before any signed-in screen
     paints) and the margin goes to 0 here.
   - Left and right: GenAIApp.css's `#root {padding: 0 8px}` (0 at 768px and below),
     which is inside body's box, so a negative margin works.
