This document categorizes the rules in theme-neon.css and its parent base.css as described in issue #639. Each section lists representative selectors and the color roles they use. The goal is to understand how the current styles map to layout, typography and other atomic groups before refactoring. See Theme Style Guide for the broader conventions used across all themes.

Category	Examples	Color Roles
Layout	.panel, .card, .navbar, .search-bar, grid/flex helpers	background, border
Typography	h1, h2, h3, p, .db-info	text, link
Controls & Forms	.btn, .dropbtn, input, select, .dropdown-content, .modal	bg, text, outline, focus glow
Tables & Lists	.url-table, .url-row-main, .tag-pill, .pagination	stripe, highlight, text
Accents & Icons	.accent, .badge, .icon, .tag-pill button	accent, hover-accent
States	:hover, :active, :disabled, .error	hover, active, disabled, error
Utility	.mt-1, .d-flex, .spinner, .hidden	n/a

• .panel, .card, .table-container – panel backgrounds and borders using --bg-panel and --border-color.
• .navbar, .controls, .menu-row – flex and grid positioning utilities.
• .search-bar, .search-history-box – container blocks for forms and history pills.

• h1, h2, h3 – header colors pulled from --font-accent.
• .db-info, .fw-bold – bold text helpers.
• Base rule * { color: #ffffff !important; font-size: 14px !important; } in base.css sets universal text defaults.

• .btn, .btn--small, .bulk-action-btn – button styles with border and background variables.
• Form elements input, select, textarea – share background, color and border from --input-bg and --input-border.
• .dropdown, .dropdown-content, .dropbtn – dropdown menus with focus and hover states.

• .url-table, .url-row-main – table layout and zebra striping via border colors.
• .tag-pill, .search-history .tag-pill – pill-shaped list items with accent gradients.
• .pagination – numbered list with flex layout and hover transition.

• .accent and links (a) – use --font-accent for highlight color.
• .tag-pill button – small delete icon inside pills.
• .icon classes in base.css for small inline images.

• Hover effects on .btn, .dropbtn, .tag-pill and navigation items adjust opacity or background color.
• Active/disabled styles come from pseudo classes on buttons and inputs.

• Margin and width helpers such as .mt-1, .ml-05, .w-100.
• .spinner animation and .hidden display control.

This inventory provides a baseline for future refactoring steps where colors will be normalized into variables and the theme engine will manage them dynamically.
