.sb-sheet as the More card (mobile.more): scrim-nested sheet, the scrim ends at the top of the bar (73px — the nav row; 123px while a list's search row shows), so the bar stays visible and the lit item stays lit; .sb-sheet-grab overlaid on the header (top 4px, centered); .sb-sheet-title = container name + .x close, min-height 48px, padding 4px 12px 4px 16px, with a full-width 1px gray-06 divider directly beneath (matches production ModalPageAppBar — ruling 27, 2026-09-23); .sb-viewlist of .sb-viewitem rows = .vi-ico · .vi-label · .vi-count — the count is text only, one neutral color (t-tiny gray-02, no chip; rules 27 + 29), and only Inbox 60 · Contacts 9.9K · Showroom 2 carry one (rule 30); current row .on (gray-06). No user row, no search field, no second list. The sheet is content-height (no fixed 70% — the six-row CRM card and the three-row Reports card differ in height). Rows are the container's sections in IA order, with a count only on Inbox, Contacts and Showroom — the three counts the app computes (rule 30; Leads, Tasks, Calendar, Reports and Settings rows carry none): CRM → Inbox · Contacts · Showroom · Leads · Tasks · Calendar; Reports → Sales · Marketing · Audiences; Settings → Profile · Dealership · Team · Deal Defaults · Automations · Templates. Tap a row: card closes, screen swaps in place (no back-stack entry — a section switch, exactly like the old tab tap), title updates, memory records the row (Showroom is remembered as Showroom, not Contacts). Scrim, X or the lit bar item again: closes. One widget in code, fed by the nav tree's sections for the lit container. Two doors, two jobs — same screen, two taps. On Contacts, Sales or Dealership, tapping the title opens that container's section card (only its sections: CRM's six rows; Reports: Sales · Marketing · Audiences; Settings' six rows). Tapping More opens the full More card (user row, Reports and Settings accordions, Help & Support, Switch dealership, Log out). More's accordions enter Reports or Settings; the title then moves sideways between their sections. CRM is its own bar item, so on CRM both the title and a re-tap of lit CRM open the CRM card; More still opens the full More card. (CPO ruling 2026-09-25)
