 * THEME-MATCHED (updated) — this tool's colors now follow the Myanas
 * theme's own purple/cyan palette (inc/design-tokens.php), by explicit
 * request. Values are stored as "H S% L%" triplets (the format
 * hsl(var(--x)) / Tailwind's CDN config expects), converted 1:1 from
 * the theme's hex tokens:
 *   --background       -> --bg-deep
 *   --foreground        -> --text-primary
 *   --card / --muted    -> --bg-surface / --bg-elevated
 *   --primary           -> --cyan-bright
 *   --accent            -> --coral-bright (the theme's purple accent)
 *   --border / --input  -> derived from --border-subtle's hue, but at a
 *                          higher lightness than the old value so the
 *                          border is actually visible against the very
 *                          dark background (the previous 24% lightness
 *                          was too close to the background's 8%).

/* FIX (width/overflow safety net): this tool's Tailwind build has
   Preflight disabled (see electricity-calculator-tailwind.css's header
   comment), so it never got Tailwind's usual global box-sizing reset.
   Any element combining a width utility (w-full, p-4, etc.) with a
   border or padding is therefore sized under the browser's default
   content-box, where border/padding is added ON TOP of the declared
   width instead of inside it -- the same class of bug already found
   and fixed for other tools' inputs/selects in this plugin. Scoped to
   this tool only, so it stays a bug fix, not a redesign of anything
   outside .ashraf-elec-calc. */

/* FIX (mobile horizontal overflow): CSS Grid items default to
   min-width: auto, meaning a grid child won't shrink below its own
   content's intrinsic width no matter what width utility (w-full etc.)
   is on the element inside it. The unit-input grids (2-col peak/off-peak,
   3-col peak/off-peak/super-off-peak in electricity-calculator.js, and
   the meter-type/load 2-col grid) have no "grid-cols-1" mobile fallback,
   so on narrow phones each <input>/<select>'s native min-content width
   was forcing the whole grid — and the page — wider than the viewport,
   cutting the tool off / creating horizontal scroll. Resetting min-width
   to 0 on every direct grid-item lets them shrink to the track width as
   intended, with no visual change on screens where it already fit. */

/* FIX (mobile horizontal overflow, ~5px leftover on the right): the same
   min-width: auto default that affects grid items above also applies to
   Flexbox children, and this tool's rows (name-input/unit-input/badge in
   each .user-row, the summary/result-card rows, the CTA and stat rows,
   etc.) are all built with Tailwind's .flex / .inline-flex, not .grid --
   so the earlier ".grid > *" rule never touched them. Each of those rows
   still had at least one child (typically a text input or label) sized
   to its own min-content width, which on narrow phones pushed the row --
   and the page -- a few px past the viewport. Since the overflow was
   sub-pixel-small it didn't create a visible scrollbar; it just meant
   the page's right edge (and therefore the tool's right padding) started
   a few px past x=viewport-width, so the padding was clipped along with
   it. Resetting min-width to 0 here lets every flex child shrink to fit
   its row instead of forcing the row wider than its container; elements
   that must stay a fixed size (shrink-0, explicit width utilities) are
   unaffected since flex-shrink: 0 already stops them from shrinking. */

        /* FIX (mobile width getting cut off): a .user-row (main meter row
           and every "সাব-মিটার যোগ করুন" row added by JS) lays out
           name-input(flex-1, min-w-80px) + unit-input(w-20 = 80px,
           default flex-shrink:1) + badge/remove-btn side by side with
           flex-wrap:nowrap (the Tailwind default). On real mobile
           widths the two inputs' own floors (80px + 80px) don't fit next
           to the badge/remove-btn inside the card's padding, so the row
           overflows its container. .at-tool-page-embed's overflow-x:
           hidden (tool-pages.css) then silently clips that overflow
           instead of letting the page scroll -- which is exactly what
           shows up as the row's right edge (the unit input / ✕ button)
           being cut off on a phone. Narrowing unit-input to a fixed,
           non-shrinking width and letting name-input's floor drop below
           80px only below 480px keeps both inputs fully visible instead
           of fighting for space they don't have. */
