/**
 * Lumbridge HQ — the reference office pack, and the file you copy.
 *
 * Pure data against `src/interiors/types.ts`. One level, fifteen rooms, three
 * hundred props and seventy-six seats, on a 34 x 18 m floor plate: a
 * lobby, an open desk floor, three meeting rooms at three different sizes, a
 * strip of focus booths, a kitchen, a lounge, a quiet room, a workshop, a server
 * room, a store, and the circulation that ties them together.
 *
 * **This file is the dev kit.** It is not here because Lumbridge needs an office
 * in a repo; it is here because a stranger who clones this should be able to
 * open one file, recognise a floor plan, change six numbers and have their own
 * office. So the dimensions are real ones — 2.8 m ceilings, 0.9 m doors, 1.6 m
 * desks, 1.8 m corridors — and the reasoning is on the page next to the numbers
 * rather than in a design document nobody reads. `src/offices/README.md` is the
 * companion: it explains the format, this explains the choices.
 *
 * The engine still knows nothing. A room called "Alcatraz" is a polygon with a
 * label, `colorKey: "focus"` is an opaque string, and seat `eng-04` is a spot on
 * the floor with a name. Nothing here tells the renderer that anybody works in
 * this building — see ARCHITECTURE.md §3.3, and the note on `Presence` in
 * `interiors/types.ts`, which is the same rule one level in.
 *
 * ### The coordinate frame
 *
 * Metres, `1 unit = 1 m`, the floor on the XZ plane with +Y up. The origin is
 * the **north-west corner** of the slab, +X runs east and +Z runs south, so in
 * plan view — looking down, +X to the right — +Z goes *down the page* and the
 * glazed façade along `z = 0` is at the top.
 *
 * Calling one edge "north" is a convenience for reading this file and nothing
 * more. An `Office` has no orientation on the earth and no sun; it is not a
 * city. If you rotate the whole building in your head, the only thing that
 * changes is the vocabulary in these comments.
 *
 * ### Which way things face
 *
 * `Yaw` is `object.rotation.y`: zero points at −Z, and the angle increases
 * counter-clockwise seen from above. An asset's **front is at −Z and its working
 * side at +Z** (`src/assets/office/common.ts`), which combine into one rule that
 * covers every prop in this file:
 *
 * > A prop takes the yaw of *the wall it backs onto*, and a seat takes the yaw
 * > of *the direction the occupant looks*.
 *
 * So a shelf against the north wall is `NORTH`, a locker against the east wall
 * is `EAST`, and someone at a desk that also reads `NORTH` is looking north at
 * it. Both halves fall out of the same convention, which is why a `DeskBank`
 * can hand one `rotation` to a desk, its chair and the seat between them.

/**
 * The fifteen slabs.
 *
 * A `Room` is a floor finish with a name and **implies no walls** — the walls

 * That means an open plan is simply rooms with nothing standing between them:
 * the lounge, the kitchen and the desk floor share three edges and only one of
 * those edges carries a wall.
 *
 * `ceiling: null` means no ceiling at all, and nearly every room here declares
 * it. The reason is the establishing viewpoint: an office you look down into
 * cannot have lids on the rooms you are trying to look into. The booths, the
 * server room and the store keep theirs, because those are the three rooms you
 * are never meant to see inside, and a ceiling is a cheap way of saying so.
 *
 * Order matters in one respect: `Plan.roomAt` resolves later rooms first, so a
 * room laid on top of another wins the lookup. Nothing here overlaps — the open
 * floor is notched around the booths rather than passing underneath them, since
 * two coplanar slabs at y = 0 is a z-fight waiting for the wrong GPU.

// ---- Desk banks -----------------------------------------------------------

/**
 * Thirty-nine desks in five declarations.
 *
 * `Plan` expands each of these into a desk prop, a chair prop and a seat per
 * station, with ids you can predict without running anything: seats are
 * `${seatPrefix ?? id}-01` counting along each row and then down the rows, and
 * the props are `${id}-desk-01` and `${id}-chair-01`. Seat `eng-04` is the
 * fourth desk in the front row of the window bench, today and after the next
 * six edits to this file, which is the property a `Presence` needs.
 *
 * ### Why every bench is two rows and not four
 *
 * `facingRows` turns the first row of each pair around so a pair shares a run
 * of desktop — a bench, rather than two rows of people looking at the back of
 * each other's heads. It does that at the bank's single `rowPitch`, and the
 * pitch that makes two rows meet back-to-back (0.85 m, a desk deep plus a cable
 * trough) is nothing like the pitch you need between one bench and the next
 * (2.4 m of chair, aisle and chair). One bank cannot express both, so a second
 * bench is a second bank. That is a real limit of the format and not an
 * oversight; the alternative is a per-pair pitch field that exists to describe
 * one furniture layout.
 *
 * The four floor banks sit in two rows of two with a 1.3 m aisle up the middle,
 * and the workshop's is a single row of three against the south wall.

 * as a prefix so that a prop id is legible on its own — `alcatraz-display` tells
 * you where to look; `prop-142` does not.
 *
 * ### On monitors, and the thing this pack deliberately does not do
 *
 * There are thirty-nine desks here and no monitors on any of them, which at
 * first looks like an omission. `DeskBank` places a desk and a chair and no
 * third thing, so monitors would be thirty-nine hand-written props that have to
 * be kept in step with a bank you are going to move next week.
 *
 * The format's answer is the asset override. Register
 * `acme:desk.workstation` with `overrides: "tera:desk.workstation"`, build a
 * desk with a monitor on it, and every station in every bank in every pack has
 * one — with no edit to this file, and no fork. That is the mechanism working
 * as designed, and it is why the monitors that *are* here are the ones that
 * belong to a place rather than to a desk: reception, and the two meeting rooms.

 * repo can highlight it, filter against it or count what is inside it. Whether
 * "eng" is a team, a cost centre or a colour scheme is not the engine's
 * business — the same rule as `Marker.colorKey`, which is why there is no
 * `kind` field to be tempted by.

/**
 * Five poses, and the first one is where you arrive.
 *
 * `viewpoints[0]` is the arrival pose. `interiors/types.ts` suggests putting
 * reception there, and this pack does not: arriving inside a room before you
 * have seen the shape of the building is disorienting in a way that a plan view
 * is not, so the establishing shot goes first and reception is second. That is a
 * choice a pack gets to make, which is the point of the field being an order
 * rather than an id.
 *
 * `distance` is metres from the target to the camera and `height` is metres
 * above this level's floor. An office is not a city: 30 m is the whole building
 * and 6 m is standing on a mezzanine, where the equivalent city numbers are in
 * the hundreds.
