…th custom UI - Change .platform-spacer background from #0d1117 to transparent so desktop mode spacers blend with the card's blob color atmosphere instead of showing as disconnected black bars - Replace native <input type="color"> with a custom dark-themed dropdown panel featuring hue/saturation/lightness sliders, a hex input field, and a color swatch — all styled to match the site's design language - Custom picker trigger dot shows the currently selected color and toggles the panel; clicking outside closes it; sliders and hex input update the card theme in real time via the existing applyCustomTheme() function https://claude.ai/code/session_017TmeQjTsBv6cvi5hnVefwX

This new trigger reuses the .theme-dot class but has no data-theme, so bindEvents() includes it in elements.themeDots and calls applyTheme(undefined) when it is clicked. That path dereferences THEMES[undefined] and throws, and it also sets currentTheme to undefined before crashing, which can break later generatePreview() calls after a user opens the custom picker.

There was a problem hiding this comment.
Calling updateFromSliders() during initialization immediately invokes applyCustomTheme(hex), which overrides currentTheme right after applyTheme(DEFAULT_THEME) runs and clears the preset active-dot state before any user interaction. This changes default behavior from preset blue to custom on every load and makes theme selection state inconsistent.

Initialization force-switches the app into custom theme mode.
Line 350 calls updateFromSliders(), and Line 324 then calls applyCustomTheme(hex). This overrides the default/preset theme state on load.
🐛 Proposed fix
- function updateFromSliders() {
+ function updateFromSliders({ apply = true } = {}) {
const h = +hueSlider.value, s = +satSlider.value, l = +litSlider.value;
const hex = hslToHex(h, s, l);
swatch.style.background = hex;
hexInput.value = hex;
trigger.style.background = hex;
- trigger.classList.add('active');
satSlider.style.background = `linear-gradient(to right, hsl(${h},0%,${l}%), hsl(${h},100%,${l}%))`;
litSlider.style.background = `linear-gradient(to right, hsl(${h},${s}%,10%), hsl(${h},${s}%,50%), hsl(${h},${s}%,90%))`;
- applyCustomTheme(hex);

Hex input path does not sync slider positions.
When a valid hex is typed, Line 346 updates theme but leaves H/S/L sliders unchanged, so the next slider move can jump to an unrelated color.

Custom picker trigger is not keyboard-accessible.
The trigger on line 38 uses a <div> with only a click listener, blocking keyboard access entirely. With the native color input hidden (CSS display: none), there is no keyboard fallback. Additionally, labels for the sliders (lines 46, 48, 50) lack for attributes, preventing proper semantic association.
