/* =====================================================================
 * styles.css  --  THE ONLY CSS FILE for media_uploader
 * =====================================================================
 *
 *   Owner rule (RobZon 2026-05-11):
 *     Every user-visible text string in this site is defined HERE as a
 *     CSS custom property, then surfaced into HTML via a placeholder
 *     element + the `::before { content: var(--name); }` pattern.
 *
 *     To rebrand the site (banner, tab labels, button captions, etc.)
 *     change ONLY the values in the ":root { ... }" block at the top of
 *     this file.  The HTML/JS/PHP never has to be touched.
 *
 *   Layout rule: phone-friendly from day one, breakpoint at 900px.
 *   Text rule:   solid color text only, NO shadows / outlines / glow.
