You are building an interface for Millwright, the flagship suite from Dunn Harland.
Millwright is an agentic layer that works inside systems the customer already runs.
Its whole promise is control, so the design must read as restrained and evidenced.

MARK
  The mark is a coupling: two ink shafts, a square orange coupling, and one
  centreline running through all three. Power only transmits if both halves
  share a centre — the discipline in one image. The centreline uses the ISO
  convention (long dash, short dash: 22 5 4 5, faint) and sets solid below
  48px. Shaft ratio is locked at 2.385:1 (62:26) in every variant; the ink
  fills the middle half of a 200×120 construction box. Orange lives on the
  coupling and nowhere else. In one-colour contexts use the mono variant
  (everything currentColor). Never rotate it, never offset the shafts, never
  shorten a shaft to fit, never add a gear.
  Sub-product marks keep the shafts and centreline and change only the centre
  element: Records is a stacked register, Agent is a solid square, Pipelines
  is a flange pair. One family, four silhouettes.

TYPE
  The Millwright wordmark is Playfair Display SC — 400, cap plus small caps,
  kerning off, line-height 0.82 — identical to the parent's construction:
  Millwright is a peer brand, not a product line. Playfair appears in the two
  wordmarks and nowhere else. Decks, interfaces and charts are Geist; Geist
  Mono, tabular, for every figure, ID, tolerance and table header.

COLOUR (Tailwind tokens, defined in src/app/_brand/tokens.ts)
  brand-orange      #FB923C  MARK ONLY       The coupling, and nothing else. Shared with the Dunn Harland quarter-circle, which is what makes Millwright read as a sibling.
  brand-amber       #F59E0B  WORKING ACCENT  Interfaces and decks. Marks one element per screen. Past roughly 10% of a surface it is too much.
  brand-amber-deep  #B45309  SMALL TEXT      Accent text and links on ground, where amber would not hold up.
  brand-ink         #111827  SHAFTS, TITLES  Sampled from the parent logo. Titles, shafts, dark surfaces.
  brand-muted       #6C6C6C  BODY            Body prose. Most words on any page are this colour, not ink.
  brand-faint       #9CA3AF  CENTRELINE      The centreline, mono labels, table headers, captions.
  brand-tint        #FEF6E7  WARM PANELS     Marks where the change path lives: at most one tinted panel or callout per screen, never the page ground.
  brand-ground      #FFFFFF  NEVER CREAM     The page and every card. White — never cream, never gradients.
  brand-success     #16A34A  SEMANTIC ONLY   Only where data is genuinely good — a stock-cover improvement, a closed exception. Never in the mark, never decoratively.
  brand-line        #E3E3E3  RULES, CARD BORDERS Rules and card borders, 1px.
  brand-surface     #F7F7F7  PANEL FILLS     Panel fills. Structural depth is drawn with fills and hairlines; floating cards may add one soft shadow.

RULES
  CLEAR SPACE — One coupling height — which is the wordmark cap height — clear on all four sides. The centreline may run into that space; nothing else may. Clear space is not baked into the files: they crop tight to the ink.
  CONSTRUCTION — Not negotiable: the shaft ratio is 2.385:1 (62:26) in every variant. Never shorten a shaft to fit a frame — heavier means taller and proportionally longer, and to fit a square you scale the whole composition. In lockups the coupling equals the wordmark's cap height and aligns to its cap top and baseline; the scale is cap ÷ 60.
  PAIRING — Next to another logo, match cap heights, never box heights. The Dunn Harland logo stacks two words, so its cap height is 0.458 of its box; equal boxes make the Millwright letters 2.18× larger, which looks like a mistake because it is one.
  THE ACTION LAYER — Orange #FB923C owns what the visitor can do: fills on primary actions, the title-block bar, chips and marks — always carrying ink content, never white. Everything informational stays ink on paper. Orange as text is always amber-deep.
  THE SHEET — Every surface is one ruled drawing sheet: hairline panel borders structure the page edge to edge, with mono corner labels in brackets. Rounded, soft-shadowed cards float on the square ruled sheet — structure is drawn, interaction is lifted.
  NO GREEN — Green stays semantic. #16A34A only where the data is genuinely good — a stock-cover improvement, a closed exception. Never in the mark, never decoratively.
  MONO FOR DATA — Runout figures, tolerances, shim thicknesses and IDs are always Geist Mono with tabular figures. It reads as instrumentation and keeps columns honest.
  SMALL SIZES — Below 48px the dashed centreline collapses: swap to the solid-centreline variant, and the favicon crops to shaft stubs around the coupling. Below roughly 200px of lockup width the endorsed eyebrow stops being readable — drop to the plain horizontal lockup rather than shrinking it.
  THE DATUM LINE — Charts carry the identity in exactly one place: a target, tolerance band or known-good baseline drawn with the ISO centreline lifted off the mark (dasharray 22 5 4 5, faint). It means what it means in the mark: this is true, measure against it. One series carries amber; five series is the ceiling.
  REVERSE — Confirmed: on dark grounds the shafts lift to #F3F4F6 and the centreline to #4B5563; the coupling stays orange. Reverse wordmark and eyebrow follow the same values.
  SINGLE COLOUR — In one-colour contexts the whole mark sets in one colour (the mono variant). The coupling reads by its gaps and height, never by a grey substitute — if the gaps are not visible, the mark is too small.
  DON'T — Don't rotate the mark, don't offset the shafts to “show misalignment”, and don't add a gear. The joke wears out and the mark stops meaning anything.
  The page is a warm paper sheet ruled with hairlines; white cards and cells sit
  on it. Ink sections separate chapters. Floating interactive cards may carry
  one soft shadow; drawn structure never does.

DUNN HARLAND (the parent brand — endorses Millwright, never leads its pages)
  Mark: the orange quarter-circle (#FB923C), shared orange with the coupling.
  Wordmark: Playfair Display SC — the same construction Millwright's wordmark uses.
  #FB923C  THE QUARTER-CIRCLE The mark's only colour. Shared with the Millwright coupling — the one value that makes the two read as family.
  #F59E0B  HIGHLIGHT          Highlight chips and emphasis on the consultancy surfaces. The value Millwright later adopted as its working accent.
  #60A5FA  UNDERLINE          Thick underline decoration on key nouns. Dunn Harland only — never appears on a Millwright surface.
  #F5F5F4  GROUND             The consultancy site's warm ground.
  #334155  WORDMARK, NAV      The wordmark and chrome ink.
  #374151  HEADINGS           Heading ink on the consultancy surfaces.
  The parent signs Millwright work (endorsed lockup, footer, contract); it never
  appears twice on one screen, and its blue never appears on Millwright surfaces.

VOICE
  - State the observation, then the inference, then the confidence. Never blend them.
  - Numbers come from real runs. If a figure is an estimate, the page says so on the same line.
  - “Not verifiable” is an allowed verdict. Thin evidence is rated zero, not assessed.
  - Sentence case everywhere. No exclamation marks. No claims about the competition.
  - The system never decides on the customer's behalf — copy must never imply otherwise.
