/*
 * "Отправить проект или ТЗ" modal — phase 5D. Reuses hero-form field styles
 * conceptually but stays a self-contained dialog on the dark surface tokens.
 *
 * Compaction pass: dialog is sized/packed to fit whole on normal desktop
 * viewports (1280x720+) without an internal scrollbar. The OUTER overlay
 * (.project-tz-modal) is the scroll container — it only actually scrolls
 * when the dialog doesn't fit (short viewports / mobile), so there is never
 * a nested scrollbar inside the card itself.
