/* Shared form controls and buttons.

   This replaces four divergent copies of the same input rule:

     .bld-row input          12.5px / 6px 8px / --bg  / focus --border3 (grey)
     .bld-pixel-control      a verbatim copy-paste of the above
     select.sel, input.srch  12px   / 5px 8px / --bg2 / focus --blue-text
     .review-field input     a fourth set, in agent-actions.css

   So the builder focused grey and the toolbar focused blue on the same
   screen, and heights were unset (except one hard-coded 32px) so controls in
   a row never lined up. Everything here is one 30px height, one focus
   treatment, and one error treatment that reuses the focus ring geometry.

   Markup shape:

     <label class="fld c-3">
       <span class="fld-label">daily budget</span>
       <input class="ctrl" type="number">
       <span class="fld-hint">Minimum $5 on this account.</span>
     </label>

   A <select> needs nothing extra — .ctrl draws its own chevron as a background
   image, so adopting the control on existing markup is just adding the class.
   .ctrl-wrap is optional, for the rare case something needs to be positioned
   against the control. */

/* ── field ──────────────────────────────────────────────────────────────

   micro-caps belong to .bld-section h3 alone. */
