 * @IMPORTANT NOTICE: Developers working on these files MUST update and maintain the Developers Change Log, failure to do is not an option:
 * !==================================================================================================================================================================
 * VERSION 1.0.0.5
 * - File Modified | Ary van der Pijl | 2026/07/20 | QA-124 | .btn-sm/.btn-icon.btn-sm resolve to 36px (--input-height-sm), under the 44px touch-target minimum - it's the standard row-action button (View/Edit/Delete) in tables across ~30 view files. Added a max-width:767px rule bumping it to 44px min-height only where a finger, not a mouse, is doing the tapping - desktop density unchanged.
 * VERSION 1.0.0.4
 * - File Modified | Ary van der Pijl | 2026/07/16 | QA-070 | Updated .btn-gold:hover's hardcoded rgba(184,134,11,0.35) box-shadow to rgba(192,138,14,0.35), matching the refreshed --color-gold-700 value in tokens.css. |
 * VERSION 1.0.0.3
 * - File Modified | Ary van der Pijl | 2026/07/11 | CSS-003 | Replaced repeated untokenized rgba(0,0,0,0.15) box-shadow value with --overlay-black-15. |
 * VERSION 1.0.0.2
 * - File Modified | Ary van der Pijl | 2026/06/19 | STANDARDS-COMPLIANCE | Applied ATH Solutions 2026 coding standards. |
 * VERSION 1.0.0.1
