… S-curve The block/small/shadow styles rendered text at a FIXED 24px font and resized that to the target grid with default bicubic: wide targets upscaled a small blurry render, bicubic rang at edges, and anti-aliased strokes mapped through the ramp as a halo of light characters — 'I see you' at width 60 was unreadable scatter. Now: one measured re-render sizes the font so each output cell averages ~8x8 source pixels; BOX resampling gives true per-cell coverage; and a contrast S-curve (0.18..0.82 stretched to 0..1) collapses edge halos while keeping genuine midtones. Captions inherit all of it via caption_lines. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- Caption positions grow beyond top/bottom: left/right run the text rotated 90 degrees along the side (book-spine style, sized against the art height); the four corners are sugar for top/bottom with forced alignment; 'wrap' flows the text clockwise as a 1-char marquee frame around the whole piece. Works in colorized ANSI, HTML, and the plain path; image-sampled caption colors use the adjacent side strip. Animated/video sinks stack caption rows, so side/wrap fall back to bottom there with a warning. - Centered captions expand out of their middle while dragging - each pixel adds width both directions so the text stays visible under the cursor - instead of only growing rightward. - Resize rings step aside for side/wrap layouts (the measured block changes in both axes); the number knobs still apply.

Summary
The density text styles were soft/fuzzy ('ever so slightly off', and outright unreadable at some widths). Three compounding causes, all in

I see youblock style: unreadable mid-ramp scatter → solid legible strokes. At width 90 the improvement is dramatic (smooth curves, filled strokes). Captions inherit everything viacaption_lines.Test plan
