/**
 * bip-style.css
 * Batch Image Processing and Gallery (BIP) - shared stylesheet
 *
 * Used by all four pages: bipa.php, bipga.php, index.php, process_log.php.
 * Consolidated from what were four separate <style> blocks. Where the
 * same class existed on more than one page with the same definition,
 * it appears once here. Where a page's controls are unique to it, the
 * section is labelled with which page(s) use it. Where two pages used
 * the same class name for genuinely different visual purposes, a
 * small page-scoped override class keeps each page looking exactly as
 * it did before this consolidation - see the "PAGE-SPECIFIC OVERRIDES"
 * section near the bottom.
