/* ═══════════════════════════════════════════════════════════════════════════
   The public bars — the top bar and the footer of the public pages, ONE file for both
   sites: the game's (landing, sign-up, login, legal: `PublicShell`/`PublicFooter`) and the
   studio's (`public/studio/index.html`, static HTML outside the SPA).

   Why a shared stylesheet and not a shared component (decision of 03/10/2026): the
   studio page is a static file on purpose — it moves to the studio's own domain by being
   copied — so the two markups stay separate. What must NOT stay separate is the drawing:
   until this file the two footers were "the same footer" written twice, and they had
   drifted (one boxed at 76rem, the other full width; links in mono on one and in the body
   face on the other; icons of 26px against 1.625rem). Now the geometry lives here, the two
   pages only choose a THEME, and `e2e/public-bars.spec.ts` measures both and fails when
   they part ways. Edit here, and both pages change together.

   ⚠️ Lengths in `px`, not `rem`, on purpose: the game's `rem` is fluid (16→21px with the
   window and the interface scale, Design do Jogo §13.8) and the studio's is not, so the
   same `2rem` drew 33px on one page and 32px on the other.

   Served from `public/` and linked by both pages' HTML (`index.html` of the SPA and the
   studio's), so it is NOT bundled or hashed: a change here reaches both at once.
