/*
 * KTDB.NET — Frontend Redesign
 * Modern layout system for the existing GeneratePress-based theme.
 *
 * IMPORTANT: no global element reset (no Tailwind-style preflight) is
 * applied here on purpose. Several bundled plugins (kitu-khoang-trong,
 * ktdb-chunguoc, kituiam, ...) print raw <button>/<input>/<textarea>
 * markup straight into post content and rely on either their own CSS or
 * sane browser defaults. Resetting those tags globally would silently
 * break their UI even though we never touched their code.
 */

/* ============ Mobile overflow fix (Core Web Vitals / Mobile-Friendly) ============ */
/* Root cause: dequeuing GeneratePress's own all.min.css (done for the redesign)
   also removed its universal box-sizing:border-box reset, and it was never
   re-added here. Using box-sizing:inherit (not !important) means any plugin
   that sets its own box-sizing on specific elements (e.g. Bootstrap loaded by
   name-generator-pro) still wins locally -- this only fixes the elements that
   had no box-sizing rule at all. overflow-x:hidden on html/body is a hard
   safety net for anything still spilling out (verified via live iframe test
   against #primary / .row.ktdb-nho, which were the confirmed offenders). */
html { box-sizing: border-box; }
*, *::before, *::after { box-sizing: inherit; }
html, body { overflow-x: hidden; max-width: 100%; }
img, video, iframe, table, embed { max-width: 100%; height: auto; }

/* WordPress's [caption]/image-caption block writes an inline style="width:NNNpx"
   on .wp-caption using the image's native pixel size (not responsive). This
   was the actual root cause found while live-testing #primary at 424px width:
   it's a plain block element with a hardcoded pixel width, so it doesn't
   respond to flexbox min-width:0 at all -- it just forces every ancestor in
   the flex chain (#primary, #content) to expand to contain it. !important is
   needed to beat the inline style. */
.wp-caption {
	width: auto !important;
	max-width: 100% !important;
}
.wp-caption img { max-width: 100%; height: auto; }

/* NOTE: an earlier attempt added `#primary { overflow-x: hidden; }` here as
   a belt-and-suspenders safety net against wide descendants. Reverted --
   setting overflow-x alone on a flex item (with align-items:flex-start on
   its .site-content parent) forces overflow-y to auto per spec, which
   collapsed #primary's height to 0 on real 390px-width test (all page
   content invisible, only header/footer showing). The .wp-caption fix
   above already removes the actual source of the overflow, and body{
   overflow-x:hidden} (further down) is a safe non-flex fallback -- no
   flex-item-level overflow rule needed. */

/* Bootstrap .row/.col-* grids are used by several bundled plugins
   (name-generator-pro, ktdb-nho). Their negative-margin .row can bleed past
   the viewport on narrow screens -- clip it without touching plugin files.
   max-width alone isn't enough: .row and .col-* are flex items whose default
   min-width:auto lets their own content (e.g. Bootstrap <input class="form-control">)
   force the box wider than the max-width cap. min-width:0 is required at
   every level of the chain to actually let it shrink. Verified against a live
   430px iframe test on the #SymbolTextGenerator (name-generator-pro) form. */
