/* ============================================================================
   unitgates.css — design tokens and components
   v0.1.0 · augustus 2026

   One stylesheet for every UnitGates surface: the consoles, the questionnaire,
   the process modeller, the website, and the HTML that becomes a PDF.

   USAGE
     <link rel="stylesheet" href="unitgates.css">
     <body class="ug">

   Everything is namespaced --ug-* / .ug-* so it cannot collide with anything
   already in the existing consoles. Adopt it a component at a time.

   SELF-CONTAINED DELIVERABLES
     Client deliverables must stay single-file. Run inline_ug_css.py to fold
     this stylesheet into a <style> block between the marker comments. Also
     drop the @import below in that case — the fallback stacks are chosen to
     hold up without any webfont.

   CONTENTS
     1. Fonts
     2. Tokens — colour
     3. Tokens — type, space, line, motion
     4. Base
     5. Typography
     6. Layout: shell, header, panels
     7. Controls: buttons, inputs, questionnaire
     8. Data: tables, badges, maturity bars, scores
     9. Process notation: steps, gates, arrows
    10. Callouts and status
    11. Print
