/**
 * Golden Lotus POS — Complete Mobile CSS  (v2 — menu-button overflow fix)
 *
 * WHAT CHANGED IN THIS VERSION:
 *   Owner phone bug: the ☰ menu button (.sidebar-toggle) was pushed off the
 *   RIGHT edge of the screen on the owner dashboard. Cause: the topbar title /
 *   meta in the owner view would not shrink, so the flex row overflowed and
 *   shoved the button out of view.
 *   Fix (Section 3 below): topbar is clamped to the viewport, the button is
 *   forced leftmost (order:-1) and static, and the title is allowed to shrink
 *   (flex:1 1 auto; min-width:0) so it truncates instead of pushing the button
 *   off screen.
 *
 * ROOT CAUSE OF ORIGINAL LAYOUT (already fixed in head.php inline <style>):
 *   .pos-main had margin-left:260px !important inline — beat every external
 *   stylesheet. head.php now drops it to 0 at <=1024px. This file handles all
 *   per-component mobile adjustments and loads AFTER that inline block.
 *
 * REPLACE the whole file at: assets/css/mobile.css
