/*
 * developments/css/dev-states.css — D76.H canonical state-template visuals.
 *
 * Visual treatment for the three states emitted by dev-states.js:
 * empty (editorial muted), error (status-error tinted), loading
 * (skeleton shimmer). All tokens from _tokens.css.
 *
 * Mode-wrapping (.panel-section--state vs .lens--state) inherits its
 * own context's spacing from devmap.css / project-panel-lenses.css;
 * dev-states.css only styles the inner .dev-state block.
