The construction rules behind every image in “Control Room”, the assets it ships, and the type argument. North star: a light operations console: paper ground, dark instrument chrome, one federal blue.

Rules
01
Construction rules
What makes two images on this page look like siblings. Derived from the shipped artifact; hold any new asset against these.
Geometry
Two grounds: paper for reading, near-black chrome for instruments — never mixed inside one component.
Pills are the only rounded thing on the page (999px); everything else is rectangular.
Hairlines come from the two-step rule ladder, never from shadows.
Color
One working accent: EBS blue #25468f, reserved for actions and links.
EBS green appears only as an 8px dot or a fill — measured 2.30:1 on this ground, so text use is prohibited.
Photography is full-color; the chrome stays monochrome so the photos read as the only warm thing.
Light & material
Photography is the client's own work: mechanical rooms, rooftops, real crews.
The hero is video behind dark chrome with white mono type — one light source, the screen itself.
Never
Green text on paper.
A second accent hue.
Rounded cards.
Stock photography — every image is the client's or the manufacturer's.

Weights measured off the embedded files. Alt text is recorded verbatim in the artifact — it doubles as the art-direction record.

EBS personnel walking a commercial mechanical room
40 manufacturer logos, PNG, embedded twice (line-card wall + ticker) — 80 files, ~1.4 MB total. Real logos fetched from each manufacturer, per HANDOFF. The EBS wordmark is the real SVG, sampled for the palette. Partner and manufacturer logos are never redrawn.
Provenance gap — flagged, not hidden
The seven photographs are the client’s own (pulled from ebssales.net per HANDOFF). The hero video’s source was not recorded during the build. Record them before any client handoff — an asset that cannot be regenerated or re-licensed is a liability in a pitch deliverable.

Environmental Building Systems represents forty manufacturer lines from two Dakota offices. A paragraph at reading size, long enough to judge the rhythm of the pairing rather than the shapes of its letters.
