 * ------------------------------------------------------------------
 * Visual identity for the Project Report tool ONLY — deliberately
 * distinct from the rest of the site so a visitor immediately reads
 * this as "a tool", not another content page.
 *
 * Design concept: an Indian bank passbook / ledger. Ruled lines,
 * hand-filled entries, an official rubber stamp — the same visual
 * language as the physical document this tool replaces. Grounded in
 * the subject, not a generic fintech gradient.
