Document Waterline environment labels and accepted banner colors #373

Delivered

Delivered in PR #374, merge 894d7c63471f7fa1a73c48c380216ff87c2e1393.

Final exact-head qualification, artifact deployment and actual Pages publication passed. All eight live monitoring guides return HTTP 200 with the waterline-environment-banner section. Each has the production variables, all six palette rows and accepted aliases, gray fallback including #ff0000, resolved embedded configuration/cache guidance and standalone service redeployment instructions. All eight actual table-of-contents links, canonical URLs and nine alternate-language entries passed. English, Japanese and Simplified Chinese were inspected at 390px in light/dark themes with legible CJK fonts and no document overflow.

Live guides: English, Ukrainian, Spanish, Portuguese, Chinese, Japanese, French, German.

This completes the website portion of Waterline #217, following merged README PR #238. It documents the deliberate CSP palette; no arbitrary-color capability or new application release is claimed. The Waterline owner receives this published-guide receipt for their own issue closure.

Original scope

Problem

The website monitoring guide explains embedded and service-mode Waterline but omits WATERLINE_ENV_NAME and WATERLINE_ENV_COLOR. Operators need a visible production label and the actual supported color contract. Waterline #217 requires this website follow-through; its README portion is merged in Waterline PR #238, source e0484aa349edd9ca567ffaeabc23216d9c908465.

Product review

Document the existing fixed CSP palette. Arbitrary colors are not requested. Embedded resolved env_name/env_color configuration and its cache remain authoritative; environment-variable text alone is not proof of the rendered state. Waterline implementation/release work stays with its SDK/UI owner.

Acceptance

• Show the name and color variables for embedded and service modes, including a production example using a supported red value.
• Document every accepted value: #0d6efd or #2563eb blue; #198754 or #28a745 green; #6f42c1 or #7746ec purple; #dc3545 red; #fd7e14 orange; #ffc107 yellow.
• State that all other values, including syntactically valid #ff0000, render gray. Do not promise arbitrary CSS colors.
• Explain embedded resolved configuration/cache precedence and the appropriate configuration refresh; distinguish service deployment environment updates.
• Update all seven translations/source hashes, pass documentation checks, and verify all eight published monitoring guides.
• Return the website PR/deployment receipt to the Waterline owner so Preserve managed runtime arguments in Cloud language continuation commands #217 can finish its external-guide requirement.
