/* BAF-PROD-009E: chrome for the public shell only - header/nav/footer, all declared directly in
   PublicLayout.razor so Blazor's CSS isolation applies normally. Page CONTENT rendered via @Body
   belongs to a different component (each individual public page) and is therefore styled by the
   separate global stylesheet wwwroot/css/baf-public.css instead - scoped CSS never crosses a
   component boundary, so a single scoped file here could never reach it.

   BAF-PROD-009E1 §5/§13: OWNER's first HUMAN review of /legal/sms-consent (then /baf/sms-consent)
   found the page too narrow, visually dense, and under-differentiated for a public trust page.
   .baf-public-main's own max-width below was widened from 760px to 880px - a professional
   "documentation site" reading width (comparable to widely-used public docs/legal sites), never
   full monitor width - and the header/footer/nav rules below gained explicit responsive treatment
   for common desktop widths, tablet, and mobile, all still expressed in existing design tokens.

   BAF-PROD-009E1A: instrumented rendered-DOM inspection (Playwright, fresh headless Chromium, no
   cache) after a full `dotnet clean`+rebuild confirmed .baf-public-main WAS actually computing to
   exactly 880px/max-width:880px with no parent constraint, isolation leak, or competing selector
   anywhere in the codebase (a repository-wide grep found .baf-public-main/.baf-public-content
   declared in exactly these two files, nowhere else) - so no cascade defect was found to "fix" in
   the literal sense of an overridden rule. The most likely explanation for OWNER's own screenshot
   still showing the pre-009E1 rendering is a stale server process or browser cache predating the
   009E1 commit (Blazor Server's own CSS-isolation bundle and structural Razor changes are not
   always picked up by hot-reload without a full app restart) - disclosed, not assumed silently.
   Regardless of that root cause, this task's own explicit numeric targets (900-1000px desktop
   content width; a draft notice that reads as "a review-state notice, not a tiny badge") were not
   yet met by 880px/the small pill badge, so both are corrected here on their own merits: max-width
   960px (comfortably inside the requested range), and the draft banner (baf-public.css) rebuilt as
   a full-width bordered notice bar instead of a small rounded pill. */
