/*
 * ===================================================================
 * READING LIST BUTTON STYLING SYSTEM
 * ===================================================================
 * 
 * This system handles reading list buttons across different user states:
 * 
 * 1. .reading-list-btn-login - Logged-out users (signup link)
 * 2. .reading-list-btn - Logged-in users (dropdown OR static button)
 *    - <select> elements: "+ Reading List" dropdown for new books
 *    - <a> elements: "To Be Read"/"Have Read" for existing books
 * 
 * CRITICAL RULES:
 * - All buttons must look IDENTICAL regardless of user state or element type
 * - NO min-height/min-width on base .reading-list-btn class
 * - Only apply sizing constraints to specific element types (select vs a)
 * - Test both dropdown and static button appearances when making changes
 * 
 * ===================================================================

/* 
 * READING LIST BUTTON STYLING - CRITICAL NOTES:
 * 
 * This class is used for BOTH dropdowns (<select>) and static buttons (<a>)
 * - Dropdowns: Used for "+ Reading List" when book not yet added
 * - Static buttons: Used for "To Be Read"/"Have Read" when book already added
 * 
 * IMPORTANT: These must look IDENTICAL to .reading-list-btn-login
 * - Same background, padding, border-radius, font, etc.
 * - NO min-height on base class (makes static buttons too tall)
 * - NO min-width on base class (makes static buttons too wide)
 * - Use appearance: none to remove default select styling
 * 
 * If you modify this CSS, test BOTH:
 * 1. Dropdown functionality (logged-in members, new books)
 * 2. Static button appearance (logged-in members, existing books)
