/* ══════════════════════════════════════════════════════════════
   UPNIXTOOLS — NON-CALCULATOR TOOL MIGRATION STYLESHEET (migrate-tools.css)
   Sirf build/tools/ ki non-calculator pages ke liye
   (Typing Speed Test, WebP Converter). site.css ko edit NAHI kiya gaya.

   RULES (task se):
   - Saari nayi classes YAHI file mein hain.
   - Koi inline <style> nahi, koi Google Fonts link nahi, kahin Syne nahi.
   - Dark theme: koi hard-coded dark text nahi — sirf theme tokens
     (--ink, --ink-soft, --muted, --faint, --accent, --green, --red,
      --surface*, --bg*, --line*). Source ke brand accents (gold #f5c518,
      webp ke soft pastel badge backgrounds) wahi rakhe gaye hain —
      ye text nahi, highlight accents hain.
   - Har non-calc tool page is file ko header ke baad link karta hai:
       <link rel="stylesheet" href="/assets/css/migrate-tools.css?v=1">
   - webp-converter source ka `:root` token override DROP kiya gaya —
     woh poori site ke theme tokens ko poison karta.
   - webp source ke `.btn-primary` / `.btn-secondary` site.css mein pehle
     se maujood hain — unhe yahan dobara define nahi kiya gaya.

   JS-MANDATED EXCEPTIONS (in-page <script> inhe naam se use karta hai,
   rename KARNA MANA hai — sirf yahan restyle kiya gaya hai):
     .tst-mode / .on       — typing mode buttons (querySelectorAll + classList)
     .tst-result / .show   — typing finish() 'show' toggle karta hai
     .tst-words .w/.c/.ok/.bad/.extra/.active — typing render() spans likhta hai
     #tst-line             — typing JS createElement karke #tst-words mein
                             prepend karta hai; render() isi mein likhta hai
     .tst-focus            — id + [hidden] se control hota hai
     .btn / .btn-gold / .btn-ghost — typing action buttons (site.css ka .btn
                             base use hota hai; gold/ghost yahan defined)
     .mode-tab / .active   — webp setMode() classList toggle karta hai
     .upload-area / .drag-over — webp drag events #uploadBox par 'drag-over'
                             toggle karte hain
     .upload-progress-box / .active — webp classList toggle karta hai
     .preview-section / .visible    — webp classList toggle karta hai
     .fmt-pill / .active   — webp querySelectorAll('.fmt-pill') + classList
     .queue-item / .queue-thumb / .queue-meta / .queue-name / .queue-sub /
     .saved / .queue-item-actions / .queue-dl / .queue-rm — webp
                             renderQueue() markup likhta hai aur wapas
                             querySelector se pakarta hai
     .compare-badge / .badge-jpg / .badge-png / .badge-webp / .badge-gif —
                             webp badgeClass() className set karta hai
   Typing ke liye ek documented bug fix hai (source bug — parent handler mein
   Backspace double-process hota tha): #tst-words wale keydown handler ke
   start mein `if (e.target === input) return;` add kiya gaya hai.
   Baqi JS dono pages par source-verbatim hai.
