Drawn with the tokens it documents, so the diagram cannot drift from the layout.

Four columns, 20px gutters. The rail stops at the centre of the first and last column, which is calc((100% - 60px) / 8) from each edge: half a column, derived from the grid rather than guessed, so it lands on centre at any width.
Content surfaces carry no fill. Rows are parted by a hairline that runs the full width of the device while its text stays on the gutter. The filled surfaces left are controls and the member pass.
18px on the phone, and every rule that bleeds past it widens by exactly that much on both sides. A divider never stops short of the edge it is meant to reach.

Member mobile app
Maestro is a ticketing and patron system for performing arts organizations, built on Tessitura. This is the member side of it: the app a subscriber opens somewhere between buying a ticket and walking into the hall.
It exists as a working prototype rather than a deck, because the questions worth arguing about here are sequence and priority, and those only become arguable once you can tap through them. The execution register carries thirty six rows behind it, and twenty one of them sit in a validate state, waiting on data or an integration that has to be authoritative before a screen can honestly show it. Two are open product decisions that block everything downstream: what your next action should actually contain, and what offline really means for the member pass.
The person this is designed for already pays the organization every season and attends more than once a year, so the app never has to sell them anything. That single fact removes most of what a ticketing app usually does and leaves a narrower job: answer what they hold, what happens next, and what they are owed, before they go looking for any of it.
The second audience is the team deciding what to build. The map is drawn for them rather than for the subscriber, which is why unbuilt work is on it and labeled instead of quietly absent.
Nine screens, four destinations, and a navigation map of the whole surface. Thirty two of the fifty one places the full navigation calls for are built; the remaining nineteen are drawn and marked as not built, and every node that has a screen behind it opens that screen when you click it.
Alongside it: an identity system covering type, color, spacing, shape, icons, components and voice, and a design system holding the composition rules, the atoms and the token layer. The typefaces are still trial and desktop licenses, so two strings fall back mid word, and the member pass shows no scannable code because there is no credential system to draw one from.
Counts on this page are read off the register and the map at the time of writing rather than kept by hand, so when they drift, the source has moved.

FT System sets headlines only. Lab Grotesque sets everything else, including all UI. FT System carries 66 glyphs, so accents, dashes and question marks drop to Lab Grotesque mid-word.
Burgundy marks the primary action and the active tab. Lemon is legal on burgundy or off-black and nowhere else — on white it measures 1.23:1. The rest is gray.
A box means these things act together. Most lists are just lists.
Separation comes from a change of ground or a hairline. The one drop shadow in the build sits under the phone chassis; every other shadow is inset.
Ratios are WCAG 2.2, computed from the token values.
L≈0.235 against L≈0.234. Beyond the unreadable pairing, burgundy set beside ink reads as an off-black rather than a color. It needs white or lemon to register.
A 3px outline at 3px offset, on every control in the build.
Where the drawn control is smaller — the view switch at 36px, the subnav at 34px — the pressable box is grown with a pseudo-element so the target reaches 44 without moving anything visible.
padding-bottom: env(safe-area-inset-bottom) on the tab bar, so the labels are not sitting under the indicator on a real phone.
Eight outlined paths, 511 × 92, no live text — so it carries no font dependency. Inlined once as a <symbol> and referenced wherever it appears.
The fill is currentColor. Burgundy on light grounds, off-white on burgundy. Never recolored by hand.
18px in the prototype bar, 30px on the splash, 46px here. 18px is the floor — below that the stacked bars of the mark stop separating.
Half the lockup’s height on every side, measured from the bounding box. Nothing sets inside it.
