     itself carries the accent so the affordance reads as a button —
     this is THE entry point back to the cabinet and the ambient
     "you are signed in" indicator. On /me/* pages the button fills
     solid phosphor so the user sees at any time they are inside the
     authenticated area.

     Sizing matches the right-side `run a check` btn-term so both
     primary controls share the same vertical rhythm. The inner
     monogram disk is 24×24, slightly inset into the capsule's
     right edge for a tight chip-on-button look. */
