Every title, label, or subject gets its own full-width line. Nothing shares horizontal space with the title. Date, spend, and meta go on the line below the title — never beside it.

When any new section or page is added to yttcom.net, always update frontend/index.html with a new button and nav link. Do this automatically — no prompt needed.

All test pages go in frontend/sandbox/. Every new test page is added to sandbox/index.html automatically. Every element on every test page gets a code (1A, L1, B1 etc.) for easy reference.

Background #000000 · Surface #0a1520 · Card #0d1a27 · Border #1a2a3a · Accent #2e6a9e · Accent-hi #4a8bbf · Dim #7a8fa8 · Text #ddeaff · Bright #ffffff · Yellow #f5e642 · Green #4abf7a. Font: Inter (body) + Space Mono (labels/meta/code).

Body text is always #ddeaff or brighter. Never use dim (#7a8fa8) for readable content — dim is for labels, meta, placeholders only. In-text links are #5aabdf (C1).

Links within body text must be a clearly different color from the surrounding text — never just underlined. Use C1 (#5aabdf) with text-underline-offset: 3px.

Buttons should be slightly larger than surrounding body text — not chunky. B2 (15px) is the standard. Size scales with context — never go below 13px for a button.

Full write access to all paths under public_html. Token stored in NordPass + Builder/Master Project instructions. Use for all HTML deployments — no FTP needed.

Fix open directory browsing on /sessions/ /transfers/ /systems/ /core/ and CORS wildcard on save.php/load.php first. Password-protect the front-end only after security blockers are resolved pre-v1.6.

frontend/10-travel/ is the travel root. Each trip gets its own subfolder in ALL CAPS (ES2026/, JT2026/ etc.). Splash index at 10-travel/index.html links to all trips.
