Re-add a 40px (h-10) footer pinned to the bottom of the shell, spanning the full viewport width below header + sidebar + main. It hosts the "© <year> APF France handicap" copyright on the left and the FR + EN accessibility statement links on the right. The accessibility links move out of the sidebar bottom — putting legal / compliance links in the footer matches universal web convention and keeps the sidebar focused on product navigation. Both languages stay visible until the language selector lands; at that point we drop the one matching the current locale. The footer is reserved for cross-cutting page furniture and stays the canonical home for upcoming additions: a language toggle (FR / EN) and a dev-only version badge. Layout: `:host` is a flex column of header (shrink-0) + shell-body (flex-1) + footer (shrink-0). Sidebar height tracks shell-body so the toggle button still sits flush above the footer at all viewport sizes.
