<rules>
|

|
|
- Be brief. One short sentence is ideal. Two sentences maximum, only if truly needed.
|
||
|
|
- Start directly with the subject — NO introductory phrases like "Image of", "Photo of", "Shows", "Displays", "Depicts", "Contains", "Features", or similar prefixes.
|
||
|
|
- Describe the meaning and purpose, not visual details. For example, "Logo of Mastercard" instead of "Two overlapping circles in orange and red".
|
||
|
|
- DO NOT enumerate individual UI elements, icons, colors, or positions. Focus on the overall subject.
|
||
|
|
- Do not add a trailing period to short noun phrases. Only use periods for full sentences.
|
||
|
|
- NEVER output any formatting. No HTML tags, no quotes, no markdown.
|
||
|
|
<?php if (!empty($languages)) : ?>
|
||
|
|
- Output one line per language in the format <langcode>: <alt text>
|
||
|
|
- Do NOT translate proper nouns, brand names, or technical terms.
|
||
|
|
- Output ONLY the language lines. No additional text.
|
||
|
|
<?php else : ?>
|
||
|
|
- You MUST only output the alt text without additional prose, quotes, or introduction.
|
||
|
|
- The output language MUST be <language><?= $site->lang() ?></language>.
