In this PR, we add a new preview button that allows users to copy the preview SVG to their clipboard. This is especially useful to continue working in external programs like Cavalry. Hold shift while clicking on the button to copy the SVG with inverted colors.

In `@web/src/preview.ts`:
- Around line 33-40: The preview copy button is only hidden when
!window.isSecureContext, but should also be hidden when the Clipboard API is
unavailable; update setupPreviewListeners to check both window.isSecureContext
and navigator.clipboard?.writeText (or navigator.clipboard presence) before
enabling the button: if either secure context is false or
navigator.clipboard.writeText is missing, set
previewCopyButton.dataset.clipboardUnavailable = "true" and
previewCopyButton.hidden = true so setPreviewCopyButtonEnabled will never
re-enable it; reference previewCopyButton, setupPreviewListeners,
setPreviewCopyButtonEnabled, and navigator.clipboard.writeText when making the
change.

In `@web/styles/main.css`:
- Around line 324-327: The CSS rule .preview-copy-icon-clipboard uses the value
keyword "currentColor" for the fill property which violates stylelint's
lowercase requirement; update the fill value in the .preview-copy-icon-clipboard
rule (the fill declaration) to the lowercase "currentcolor" so the property
reads fill: currentcolor; and rerun linting to confirm the stylelint error is
resolved.

19-23: ⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Gate availability on writeText, not only navigator.clipboard.

The current gate can enable the button in hosts with partial Clipboard API support, then every copy fails on fallback write. Tighten the check to require writeText.

Suggested patch
 function isClipboardAvailable(): boolean {
-  return window.isSecureContext && isDefined(navigator.clipboard);
+  return window.isSecureContext && typeof navigator.clipboard?.writeText === "function";
 }

Also applies to: 94-96

In `@web/src/copy.ts` around lines 19 - 23, The current availability gate only
checks isClipboardAvailable() which can be true when navigator.clipboard exists
but writeText is missing; update the check to require the writeText method
(e.g., ensure navigator.clipboard?.writeText is a function) before enabling copy
UI: change the block that sets clipboardUnavailable and previewCopyButton.hidden
to test for navigator.clipboard?.writeText (or update isClipboardAvailable() to
include that check), and apply the same tightened check to the other occurrence
that handles the fallback (the block referenced around lines 94-96) so all copy
enabling/attempts only run when writeText is present.

In `@web/src/svg.ts`:
- Around line 343-346: The combineOpacity function misparses percentage strings
like "50%" because parseFloat yields 50 which then gets clamped to 1; update
combineOpacity to detect and handle percent-formatted opacity values (trim
whitespace, check for trailing '%'), convert percentages to a 0-1 value by
dividing by 100 before applying Number.isFinite checks and multiplying by alpha,
and keep the existing clamping logic to ensure the final result stays between 0
and 1; reference the combineOpacity function to locate and modify the parsing
branch to support both numeric and percentage opacity inputs.

track and validate a monotonically increasing preview request ID so older
