/* ============================================================================================ GIÁ THẬT GLOBAL STACKING CONVENTION (SHARED_GT_SHELL_ZINDEX_DEBT, closed 2026-08-28, Lane E) ============================================================================================ #gtShell is a sticky, always-on-top global header injected on every page (gt-shell.js). Every SPA-owned overlay (modal / drawer / lightbox / bottom-sheet) must paint ABOVE it, and every close/back CONTROL inside such an overlay must paint above its own overlay body - this has already caused two production incidents from two different SPAs independently re-deriving the same fix: the vehicle photo-lightbox close X was tap-blocked (LIVE-UI-004, fixed 2026-08-26 by remapping the SPA's own overlay band from 100-300 to 1300-1400), and the property detail close control was completely untappable on mobile (fixed 2026-08-27 by lifting the property overlay band to 1360/1362/1370). Both fixes were correct but ad hoc - this block is the one convention that replaces guessing with a documented contract, so a THIRD SPA (or a new overlay in an existing one) never has to rediscover the same bug. Bands (each a round number with headroom for an SPA's own internal ordering): --gt-z-shell the sticky #gtShell header itself (unchanged value - this file's own rule below now reads it from here instead of a bare literal, so the header can never silently drift back above the overlay bands) --gt-z-overlay first-layer SPA overlays: modal / drawer / bottom-sheet backdrops and panels (start here for anything new) --gt-z-overlay-raised a second overlay stacked above a first (e.g. a lightbox opened from inside a detail overlay), or a bar that must float above an open overlay (sticky contact bar, toast) --gt-z-overlay-controls close / back / nav controls that must NEVER end up under anything - the "always tappable" ceiling Everything already shipped already lives inside this exact numeric range BY CONVENTION, not by referencing these variables yet (xm-app.*.css: .modal 1300, .finder-modal 1310, #xmToast 1340, .lb + visual-search 1360-1400; property/public.html: .ov 1360, .stickc 1362, .bs 1370) - so nothing here changes a single existing literal and neither prior workaround regresses. New or changed SPA overlay code should reference these variables instead of inventing a fresh literal, e.g. `z-index:var(--gt-z-overlay-raised)` instead of `z-index:1360`, so the contract stays a single source of truth. Bumping --gt-z-shell here (should the header ever need to change) can never again silently outrank an overlay that was built against a stale hardcoded number. */ :root{--gt-z-shell:1200;--gt-z-overlay:1300;--gt-z-overlay-raised:1360;--gt-z-overlay-controls:1400} :root{--gt-shell-accent:#047857;--gt-shell-ink:#101828;--gt-shell-muted:#4b5563;--gt-shell-line:#e5e7eb;--gt-shell-bg:#fff} #gtShell,#gtShell *{box-sizing:border-box} /* explicit visible keyboard-focus ring - the pill/button chrome below has enough custom background and border-radius that a bare UA-default outline reads faintly against it */ #gtShell a:focus-visible,#gtShell button:focus-visible{outline:2px solid #2563EB;outline-offset:2px} #gtShell{position:sticky;top:0;z-index:var(--gt-z-shell,1200);width:100%;height:72px;background:var(--gt-shell-bg);border-bottom:1px solid var(--gt-shell-line);font-family:"Be Vietnam Pro","Be Vietnam Pro Fallback",Inter,"Segoe UI",Roboto,Arial,sans-serif;color:var(--gt-shell-ink)} #gtShell .gt-shell-inner{max-width:1320px;height:100%;margin:0 auto;padding:0 18px;display:flex;align-items:center;gap:14px} #gtShell .gt-shell-logo{display:flex;align-items:center;flex:0 0 118px;height:44px;text-decoration:none;color:inherit;border-radius:10px} #gtShell .gt-shell-logo img{display:block;width:112px;height:auto;max-height:38px} #gtShell .gt-shell-nav{display:flex;align-items:center;justify-content:center;gap:5px;min-width:0;flex:1 1 auto;white-space:nowrap} #gtShell .gt-shell-pill{display:inline-flex;align-items:center;justify-content:center;min-height:38px;padding:8px 10px;border:1px solid var(--gt-shell-line);border-radius:999px;background:#fff;color:var(--gt-shell-ink);text-decoration:none;font-size:12.5px;line-height:1;font-weight:750;white-space:nowrap} #gtShell .gt-shell-pill:hover{border-color:var(--gt-shell-accent);color:var(--gt-shell-accent)} #gtShell .gt-shell-pill.active,#gtShell .gt-shell-pill[aria-current="page"]{background:var(--gt-shell-accent);border-color:var(--gt-shell-accent);color:#fff} #gtShell .gt-shell-right{display:flex;align-items:center;justify-content:flex-end;gap:8px;flex:0 0 auto} #gtShell .gt-shell-post{display:inline-flex;align-items:center;min-height:40px;padding:8px 12px;border-radius:10px;background:var(--gt-shell-accent);color:#fff;text-decoration:none;font-weight:800;font-size:12.5px;white-space:nowrap} #gtShell .gt-shell-lang{display:inline-flex;border:1px solid var(--gt-shell-line);border-radius:9px;overflow:hidden;background:#fff} /* LIVE-UI-015: was min-width:42px/min-height:40px - under the 44x44 CSS px mobile tap-target floor */ #gtShell .gt-shell-lang button{appearance:none;border:0;border-radius:0;background:#fff;color:var(--gt-shell-muted);min-width:44px;min-height:44px;padding:8px 10px;font:800 12.5px/1 inherit;cursor:pointer} #gtShell .gt-shell-lang button.active{background:var(--gt-shell-accent);color:#fff} /* Global Notice Center trigger.
