Jeff Emmett c1295e8c81 Merge server changes: fixed-width glyph cells, Web Worker animation 
Incorporates uncommitted server-side improvements:
- VARIABLE_WIDTH_PALETTES + fixed-width <span class="c"> cells for grid alignment
- Web Worker-based animation timer (keeps running in background tabs)
- Passes fix_cells through animate_image() for animation frames

Jeff Emmett 3176a36ce6 Fix emoji/wide-char palette proportions 
Emoji, hieroglyphs, dominos, mahjong, playing cards, cuneiform,
alchemical, flora, and weather palettes use double-width characters
that display at 2x normal monospace width in browsers.

Fix: detect wide palettes and halve the render width with adjusted
aspect ratio (1.0 instead of 0.55) so the output maintains correct
image proportions regardless of character width.

Jeff Emmett 16a5dbca11 Super high-res rendering: up to 1500 chars wide 
- Width slider now goes to 1500 (was 500), default 300
- Resolution presets: Low (100), Med (300), High (600), Ultra (1000), Max (1500)
- Optimized renderer: fast pixel access via img.load(), run-length color
  grouping in HTML output (groups consecutive same-color chars into one span)
- 800-wide render in 0.5s, 1500-wide in 3.3s
- Base font reduced to 5px for ultra-dense display
- Container bumped to 4 CPU / 1GB RAM for heavy renders
- Uvicorn keep-alive timeout increased to 120s

Jeff Emmett 963096eaef Fix photo orientation and aspect ratio 
- Apply EXIF transpose so phone photos render right-side-up
- Adjust char aspect ratio from 0.45 to 0.55 to match browser
  rendering (8px font, 1.05 line-height, monospace ~0.6 w/h)
