/* ─── panels.css — the ONE compact look of every side panel (left menus and right panels). Loaded last.
 *
 *   Owner 2026-10-25: "the design is not intentional and wastes too much space" → thin one-line rows (label left, value right), small
 *   collapsible section headers, inline icon-left buttons, no decoration. Everything goes through shared classes, so a new panel that
 *   uses them (.sel3d-row, .sp-row, .numbox, .mini, .btnrow, .pop-group, details.ps, .pt-roll …) is dense and consistent for free.
 *
 *   Tokens   --u-h   row / control height (22 px; 36 px with body.is-touch — fingers)
 *            --u-gap space between rows and between buttons      --u-fs / --u-fs2  type (11.5 / 10.5 px)
 *            --u-pad panel side padding      --u-r control radius      --u-lab label column (share of a row)
 *   Levels   panel title (h3) › section (.pt-roll .pop-group .st-label .sec-title: 24 px, folds) › sub-section (details.ps: 22 px) › row (22 px)
 *   Rows     label LEFT in the mut colour, value / control RIGHT; checkboxes sit in the value column; hints are ONE line (tap = all of it).
 *   Buttons  .mini = inline, icon on the left, auto width; .btnrow wraps them; .seg = segmented control; .on = the active one.
