fix: TextPlaceholder is emty in Safari

[i-runets]

Description:

TextPlaceholder filled each fake "word" with repeated   Safari suppresses ink for whitespace glyphs, so -webkit-background-clip: text had nothing to paint the shimmer gradient onto, making the bars invisible.

Fix: replace the   filler with the letter x. In the Redacted font both characters share the same glyph/width, so layout is unchanged — but x isn't a whitespace character, so Safari renders it correctly.
