Formatting rules

• Void elements (br, img, input, etc.): self-closing <br />
• Inline elements (span, a, strong, etc.): kept on one line when short
• Block elements (div, p, ul, etc.): indented on separate lines
• Attributes: 0-1 attrs inline, 2 attrs inline if ≤80 chars, 3+ attrs multi-line
• Expressions (${...}): inline if simple, block-level if function call / arrow / multiline
• Pre elements (pre, script, style, textarea): content preserved verbatim
• Event bindings (@click.prevent.stop): modifiers preserved as-is
