/*
================================================================================
LABEL GENERATOR — styles.css  (BASE: styles_patched_v15.css)
--------------------------------------------------------------------------------
Goal of this stylesheet:
- Provide a role-based color system using the company brand palette (huisstijl).
- Keep UI readable: neutral surfaces for content, brand color for emphasis (CTA/active state),
  semantic colors for status (error/success), and clear focus indication for accessibility.
- Maintain stable layout rules for:
  - Tabs and panels
  - Single/Bulk forms
  - Preview grid + label rendering (the .label / .label-inner structure)
  - Help tab two-column quickstart layout

IMPORTANT MAINTENANCE NOTES
- Do not change selector names casually: app.js injects markup that relies on these classes.
- Colors should be changed via :root variables (tokens) first; avoid sprinkling new hex values.
- The preview placeholder is styled via .preview-placeholder (JS only toggles the class).
