/* ============================================================
   Founders Sprint — shared site chrome (nav + scroll bar + footer).

   Loaded by every page that should display the same top nav, the
   gradient scroll-progress bar above it, and the dark footer with
   the FR/EN switch. Lifted verbatim from index.html so the page
   chrome stays identical across landing, pourquoi.html, waitlist.html,
   and the legal pages.

   Pages that inherit this file should also :
     - load `assets/i18n-landing.js` (gives the footer lang switch
       its click binding + does data-i18n translation on demand) ;
     - load `assets/chrome.js` (scroll progress wiring, plus a
       small no-op shim if the page hasn't already defined the
       motion / fade-up libs).

   Token assumptions (provided by either the page :root or the
   landing's :root if chrome.css is loaded after) :
     --navy / --navy-deep / --cream / --orange / --orange-soft /
     --cyan / --line-light.
   ============================================================ */

/* Universal box-sizing reset. Without this, inputs with padding +
   width:100% inside a CSS grid cell push past their cell width and
   overlap their neighbours (waitlist/postuler row 'Prénom' + 'email'
   touched each other on 1440 px viewports — the email started 18 px
   inside the Prénom right edge). border-box makes padding count
   inside the declared width, eliminating the overflow. */
*, *::before, *::after { box-sizing: border-box; }

/* Sticky-footer scaffolding applied to every chrome page. Body is a
   flex column ; main fills the gap so the footer always sits at the
   viewport bottom on short pages (legal pages, /waitlist, /postuler
   when a form is collapsed, etc.).

   `margin: 0` on html + body kills the 8 px browser default — without
   it, every chrome-using page (pourquoi, waitlist, postuler, legal)
   sits 8 px inset from each viewport edge and the footer never touches
   the bottom of the screen. The landing nukes the default in its own
   <style> block ; chrome.css owns the reset for everyone else. */
