Short answer: implement mine (with a tiny blend of hers).

Why:

No more “blank tiles” — mine uses inline hex backgrounds, so Tailwind purge can’t strip them. That’s the root of the issue you hit.

Clearer UX — strong selected outline + check badge + aria-pressed for keyboard/screen readers.

Future-proof — no safelist maintenance when you add new styles/colors.

Hers looks nice (and added a few categories). Let’s merge the content of her grid into the robust implementation you already patched.

What to do (quick)

Keep my StyleTile (inline style={{backgroundColor: card.hex}}, selected outline, aria-pressed).

Extend your STYLE_CARDS with her extra styles/icons:

const STYLE_CARDS = [
  { id:"balanced",  title:"Balanced",  subtitle:"Geometric + Wordmark + Badge", hex:"#111827", glyph:"square" },
  { id:"minimal",   title:"Minimal",   subtitle:"Clean lines, lots of space",    hex:"#1f2937", glyph:"pipe" },
  { id:"bold",      title:"Bold",      subtitle:"Heavy weight, strong shapes",   hex:"#3f38c9", glyph:"square-filled" },
  { id:"monogram",  title:"Monogram",  subtitle:"Letter-focused marks",          hex:"#085f4e", glyph:"A" },
  { id:"badge",     title:"Badge",     subtitle:"Emblem styles",                 hex:"#075985", glyph:"circle" },
  { id:"playful",   title:"Playful",   subtitle:"Rounded, friendly",             hex:"#be185d", glyph:"dots" },
  { id:"elegant",   title:"Elegant",   subtitle:"Serif, luxury vibes",           hex:"#2b241f", glyph:"italic-E" },
  { id:"techy",     title:"Techy",     subtitle:"Futuristic, angular",           hex:"#0e5161", glyph:"diamond" },
  { id:"organic",   title:"Organic",   subtitle:"Nature, hand-drawn",            hex:"#0f5f2b", glyph:"oval" },
];


(Optional) Drop a tiny glyph overlay for each card (like in her screenshot). It’s just a neutral SVG centered in the color block; won’t affect purge:

function TileGlyph({ type }: { type?: string }) {
  return (
    <svg className="absolute inset-0 m-auto h-8 w-8 opacity-60" viewBox="0 0 24 24" fill="none" stroke="currentColor">
      {type==="square" && <rect x="6" y="6" width="12" height="12" rx="2" strokeWidth="1.5"/>}
      {type==="square-filled" && <rect x="7" y="7" width="10" height="10" rx="2" strokeWidth="0" fill="currentColor"/>}
      {type==="pipe" && <line x1="12" y1="6" x2="12" y2="14" strokeWidth="1.5"/>, <line x1="7" y1="17" x2="17" y2="17" strokeWidth="1.5"/>}
      {type==="circle" && <circle cx="12" cy="12" r="3.5" strokeWidth="1.5"/>}
      {type==="dots" && <><circle cx="9" cy="12" r="1.2"/><circle cx="12" cy="12" r="1.2"/><circle cx="15" cy="12" r="1.2"/></>}
      {type==="A" && <text x="12" y="13" textAnchor="middle" fontSize="8" fontWeight="700">A</text>}
      {type==="italic-E" && <text x="12" y="13" textAnchor="middle" fontSize="8" fontStyle="italic">E</text>}
      {type==="diamond" && <polygon points="12,8 16,12 12,16 8,12" strokeWidth="1.5"/>}
      {type==="oval" && <ellipse cx="12" cy="12" rx="3.5" ry="5.5" strokeWidth="1.5"/>}
    </svg>
  );
}

const StyleTile = ({ card, active, onToggle }: { card: any; active: boolean; onToggle: () => void }) => (
  <button
    onClick={onToggle}
    aria-pressed={active}
    className={`relative w-full text-left rounded-2xl border transition p-5 ${
      active ? "border-indigo-500 shadow-[0_0_0_3px_rgba(99,102,241,0.25)]"
             : "border-neutral-200 hover:border-neutral-300"
    }`}
  >
    <div className="relative h-28 rounded-xl mb-4" style={{ backgroundColor: card.hex }}>
      <div className="absolute inset-0 flex items-center justify-center text-white/70">
        <TileGlyph type={card.glyph} />
      </div>
    </div>
    <div className="font-medium">{card.title}</div>
    <div className="text-xs text-neutral-500">{card.subtitle}</div>
    {active && (
      <div className="absolute top-3 right-3 rounded-full bg-white border border-indigo-500 p-1">
        <svg width="16" height="16" viewBox="0 0 24 24" fill="none">
          <path d="M20 6L9 17l-5-5" stroke="#4f46e5" strokeWidth="2" strokeLinecap="round" strokeLinejoin="round"/>
        </svg>
      </div>
    )}
  </button>
);


This gives you her look with your stability. If you still prefer her Tailwind-only approach, you’ll need a safelist in tailwind.config.js and remember to update it whenever you change the palette; otherwise you risk blank tiles again.
