Jeoulmaru Weighing Inspection Office

How it was made

An information site for a fictional office that verifies scales and weights. It computes verification intervals, tolerance rulings, fees and visit bookings without a server.

A vertical ruler (0–1000 g) fixed on the left doubles as the table of contents and the alignment line. The body is an asymmetric 4:8 layout, and each section's scale label runs a leader line back to the ruler.

The scale, weight cross-section and sketch map drawings are SVG. The 7 photos appear only in the verification types and directions pages.

Ink panels #1A1F24 sit on a steel blue-grey #C9D0D6 ground in three places: header, results and footer. One pass green is used only for ruling text, the ruler needle and the current menu underline.

Type is three faces: Noto Serif KR, Noto Sans KR and Sometype Mono. The ruler needle reads scroll progress as 0–1000 g.

After a ruling the beam settles in 600ms, level or tilted 7°. The tolerance ruling compares up to 5 rows of measurement points against the allowed error per load range (1, 2 or 3 e).

The 12 pages and the data file are generated by build.mjs. Interval, fee, booking and lookup calculations share one calc.js between the screen and the generator.

Where and how to use it

Suited to inspection and calibration offices with fixed verification cycles and fee schedules. Cycle calculation, verdicts, fees, booking and receipt lookup share one reference table.

Points to check

The reference time is fixed at 2026-10-14 09:00, and the cycle, tolerance and fee tables are invented. Receipt numbers persist only in this tab's sessionStorage, and the booking calendar covers October and November only.
