Antipattern: PHP-itis (logic in views)

The smell

• Multi-clause conditionals in ERB referencing model internals
• Loops that accumulate totals, filter, or compute in the template
• sprintf / Date.today / BigDecimal math in views
• Same logic copy-pasted across templates
• Direct queries from views (<% Post.published.each ... %>)

Why it hurts

• Untestable in isolation
• Designers can't safely edit
• Triggers N+1 queries
• Encourages duplication across templates
