-- Rosary Presenter -- MySQL 8.x / MariaDB schema
-- Canonical, consolidated schema (structure only). Supersedes the old
-- install.php + migrate_v2..v6.php chain of hand-run scripts.
--
-- This file is DDL only -- every CREATE TABLE is IF NOT EXISTS, so it's safe to
-- run directly (mysql -u user -p dbname < schema.sql) against either an empty
-- database or an existing one. Seed data (site_settings defaults, the
-- superadmin account, and the standard prayer library) is NOT included here:
-- it's inserted by install.php via PHP arrays + prepared statements instead of
-- raw SQL, both because the superadmin password needs PHP's password_hash()
-- and to avoid any risk of the prayer texts' own punctuation (they contain
-- semicolons and apostrophes) being misread as SQL syntax.
--
-- For an EXISTING production install that already ran the old migrate_v2..v6
-- scripts, applying this file is a no-op EXCEPT for the new
-- users.failed_login_attempts / users.locked_until columns added for login
-- rate-limiting, and the sessions/novena_groups.photo_focal_x/photo_focal_y/
-- photo_zoom columns added for the photo reposition tool -- see README.md
-- "Upgrading an Existing Install" for the manual ALTER TABLE statements
-- needed there.
