   BioProfile - the member shell's own sheet. EMPTY since T283b-r2 (2026-09-14).

   T271b (Thursday 2026-09-11) drew the member navigation anew here: a sidebar
   the window's full height at a desk, a bottom bar with a tap sheet on a phone,
   the topbar hidden at a desk. It went to the one deployment that serves both
   hosts the same afternoon, and Jesse never confirmed it (2026-09-14 15:50: "I
   never confirmed this menu bar ... I never confirmed a new design").

   So the design is reverted: the member navigation is drawn in the design
   system's own look again (design-system/css/components.css, the pillar nav as
   it stood on T233's day, 2026-09-07), on every member page, and only for a
   signed-in session (T283b-r1). The pages keep their link to this file so
   nothing answers 404; the file holds no rule. A navigation design change comes
   back only as Jesse's own task, shown to him on a preview deployment first and
   grafted on his written yes (agency/skills/bioprofile-design-base/SKILL.md).
