   lulla-reader.css v1.0 (T123 build, 2026-07-01)
   Reading-loop styles for lulla.net. Loads AFTER custom.css.
   Pairs with lulla-reader.js. Tokens only; the ONLY hex literals
   live in the sepia token block and the corpus accent block, both
   fenced with LV-HEX-OK markers for the validator.
   Sections:
     1  sepia theme tokens (+ dark-media guards)
     2  reader vars, display utilities, stroke
     3  chapter opener (parva-tag, subtitle, post title)
     4  shirorekha divider
     5  body type bump (reader scale + leading)
     6  meta line
     7  prev/next chapter nav (.lv-chnav)
     8  progress milestones
     9  toc rail
    10  resume pill
    11  fab stack + settings panel
    12  glossary popover
    13  darshan lightbox
    14  reveal grammar (gated under html.lv-js)
    15  sound toggle bars
    16  idle toast
    17  view transitions + curtain
    18  magnetic buttons
    19  hub read chips
    20  corpus accents
    21  print
