   On phones the current page name used to sit in the header bar next
   to the hamburger, wrapping onto 3-4 lines and pushing the action
   icons out of place. Below 768px it's dropped entirely — the sidebar
   drawer / bottom nav / page's own <h1> already say where you are, so
   nothing is lost, only the cramped duplicate label. Full-width action
   row (hamburger left, icons right) gets the freed-up space. The
   full-name pill in the user menu is also hidden on very narrow phones
   (<576px) — just the avatar stays, tap it to see the name/role in the
   dropdown — the same "icon over label" trade already applied to the
   KH/EN switcher above 576px. */

/* ━━━ TABLE RESPONSIVE ━━━
   FIX (reported): .data-table used to be forced to `display: block`
   in the unscoped mobile-first BASE rules above, with no min-width
   media query ever setting it back to a real `table` display. A
   block-level <table> stops the browser's table layout algorithm
   from stretching columns to fill the container, so every list page
   (Mobile/QR Check-In Log, Employees, etc.) rendered with a big empty
   gap to the right of the table on tablet/desktop — the .table-wrap
   card looked full-width, but the <table> inside it did not.
   `display: block` is only actually needed on narrow phones (paired
   with .table-wrap's own overflow-x: auto) to allow raw horizontal
   scrolling for tables that AREN'T using the card-style `.table-card`
   layout below; from 768px up, tables go back to their normal
   `table` display so width: 100% (app.css) stretches every column to
   fill the page properly. */

/* ━━━ MOBILE BOTTOM NAVIGATION (Section 6.6) ━━━
   khmer24.com's own mobile app uses a floating, rounded-top tab bar
   with its single most important action ("Post/Sell") raised as a
   circular button that pops above the bar line. Mirrored here: the
   bar gets rounded top corners + a real elevation shadow instead of
   a flat bordered strip, and — when the signed-in user has
   attendance.checkin — "Check In" becomes that same raised circular
   center button, since it's the one action mobile/field employees
   open this app for most often. Everything else (Dashboard, Profile,
   Logout) stays a normal flat tab; the whole row still shares one
   base class so a user WITHOUT attendance.checkin simply gets a
   plain 3-tab bar with no raised button, no separate CSS path. */
