/* ===================================================================
   Hidden-state reset
   =================================================================== */
/* Component display rules (e.g. `.loading-state { display: flex }`,
   `.selection-dock`, `.sheet`) have the same specificity as the UA default
   `[hidden] { display: none }` and appear later in source order, so they
   win the cascade and the native hidden attribute stops hiding elements.
   This was observed in the wild: the viewer kept showing "Loading skill
   map..." after graph load because JS set `el.hidden = true` but the
   flex rule overrode it. `!important` restores the native contract for
   loading-state and all shared overlays/panels (selection dock, sheet,
   legend, empty-state) without affecting their visible-state display behavior. */
