# Dev Run flags and signage

Canada: official National Flag of Canada artwork, Canadian Heritage, downloaded 2026-10-02 from https://www.canada.ca/content/dam/pch/images/services/flag-canada/drapeaunational-nationalflagCanada.zip . Official PNG resampled to 400 × 200 for this small in-game flag; the artwork, 2:1 proportions and eleven-point leaf are preserved. Reference: https://www.canada.ca/en/canadian-heritage/services/flag-canada-description.html . No flag texture mirroring or invented maple-leaf shape.

United States: code-authored vector following Executive Order 10834 standard proportions: 1:1.9, thirteen equal stripes, union 7/13 high and .76 flag-heights wide, fifty five-point stars in nine alternating six/five rows. References: https://www.archives.gov/federal-register/codification/executive-order/10834.html and https://www.govinfo.gov/content/pkg/USCODE-2022-title4/html/USCODE-2022-title4-chap1-sec1.htm . Kept as an SVG to retain the actual star field at small sizes.

Billboards: original fictional Dev Run messages dominate. A minority of toolkit spotlights reuse the already sourced technology artwork in `/assets/brands/NOTICE.txt`; marks identify tools, not building occupants, employer affiliations, sponsorship or endorsement. No new third-party technology logo downloads were introduced. No physical address or claimed company office is attached to a fictional building.

Landmarks, lights, city life, scenery, signs, platforms and ceremony callbacks are code-authored stylizations. CN Tower lighting is artistic; no real-world historical lighting schedule is claimed.

The six fictional rotating sign messages dominate. Only every fourth billboard can show a toolkit mark, during one of its three eight-second phases (roughly one-twelfth of panel time). All other panels remain fictional. Flags are decoded to small reusable textures before cloth-strip rendering so SVG source-coordinate differences cannot crop away stripes or stars.
