/*
 * Per-language theme stylesheet — fallback target.
 *
 * phpBB unconditionally requests `styles/{style}/theme/{lang_name}/stylesheet.css`
 * for the active language (see {T_STYLESHEET_LANG_LINK} in functions.php),
 * with NO parent-style fallback. Stock prosilver only ships theme/en/, so any
 * other locale (e.g. de_x_sie on forum.trutzbox.de) yields a 404 — even on a
 * vanilla phpBB install. The vestigial purpose of these per-lang files is to
 * swap the `.online` user-online icon per locale; we don't ship locale-specific
 * online icons, so this stub stays empty.
 *
 * The Apache `AliasMatch` in trutzbox-rewrites.conf routes every per-lang
 * request under our style to this single file, so adding a new language pack
 * never re-introduces the 404.
