/* Impact Ledger neumorphism theme. Load AFTER style.css.
   Accessible: soft raised/inset surfaces, text >=4.5:1, visible focus rings,
   one accent hue (teal #7797a3, chosen by Arash 2026-11-08) for the primary action and progress fills.

   Class hooks expected (add any that are missing in the markup):
     .card .tile .input-box (or bare input/select/textarea) .bottom-nav .fab .btn-primary .btn
     .tile.active / [aria-pressed="true"] = inset.  .bottom-nav [aria-current="page"] = inset.

   New components (pure CSS, driven by --value 0..100 set via a class-free attribute is
   not possible without inline style, so set it from JS: el.style.setProperty('--value', n)
   or add classes/attributes in your own sheet):

   .icon-circle  raised round icon holder, 48px
     <span class="icon-circle" aria-hidden="true"><svg>...</svg></span>

   .ring  donut progress; --value 0-100; centre is inset and holds the label
     <div class="ring" role="img" aria-label="70% of weekly goal"><span>70%</span></div>

   .pill-bars / .pill-bar  vertical inset tracks, fill height = --value
     <div class="pill-bars">
       <div class="pill-bar"><div class="pill-track"><div class="pill-fill"></div></div>
         <span class="pill-label">People</span><span class="pill-value">82%</span></div>
     </div>   (set --value on .pill-bar)

   .progress  slim inset track with gradient fill, optional bubble
     <div class="progress" role="progressbar" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100">
       <div class="progress-fill"><span class="progress-tip">50%</span></div></div>   (--value on .progress)

   .segmented  raised container, accent-filled active segment
     <div class="segmented" role="group"><button aria-pressed="true">One-off</button><button aria-pressed="false">Monthly</button></div>
     (active = [aria-pressed="true"], [aria-selected="true"], [aria-checked="true"] or .active)

   .toggle  pill track + raised knob, accent track when on
     <button class="toggle" role="switch" aria-checked="true" aria-label="Still giving"></button>
     (or <input type="checkbox" class="toggle" role="switch">)
