<p>Each transaction is encrypted end-to-end for security.</p>
Note Browsers add default top and bottom margins to paragraphs. Reset or adjust with CSS if needed.

Strong & Emphasis
syntax
<strong>important</strong>
<em>emphasized</em>
example
<p><strong>Warning:</strong> This action <em>cannot</em> be undone.</p>
Note strong conveys urgency or importance (renders bold). em conveys stress emphasis (renders italic). Prefer these over <b> and <i> for meaningful emphasis, since screen readers alter vocal tone for strong/em.
Note pre preserves all whitespace and line breaks exactly as written. Wrap code inside pre for multi-line blocks. Use code alone for inline code snippets.

<hr>
<p>New section begins here.</p>
Note br is for meaningful line breaks like addresses or poetry, not for spacing. Use CSS margins or padding for spacing. hr represents a thematic shift between content blocks.
