/*
  Safety net for explicit width/height attributes added to <img> tags.
  Loaded BEFORE css/style.css so any class-based rule there (e.g. Bootstrap's
  .img-fluid, .jarallax-img, .reveal img) keeps higher specificity and wins.
  This only protects bare <img> tags that have no sizing class: without this
  rule, a browser could otherwise stretch height to match the intrinsic
  height attribute when width is constrained by an ancestor. Audited
  css/style.css: no rule sets a fixed height on an `img` selector without
  also setting width, so this rule changes nothing visually.
