/* Default songbook stylesheet. The look and proportions are tuned to
 * match the legacy SSG output (v1_legacy in style_comparisons/), with
 * additional rules for the table of contents and a few elements the
 * legacy CSS didn't cover.
 *
 * Reference numbers from the legacy computed styles:
 *   - body:           16px Times New Roman, 1% padding
 *   - h1 title:       32px (2em) Trebuchet MS bold
 *   - .sg_comment:    16px Calibri bold, margin 0 0 15px 20px
 *   - .ch:            16px Calibri italic
 *   - .ly:            17.6px Calibri (110% of body)
 *   - chord+lyric:    ~45px tall when rendered together
 *   - chorus:         cream #fefedd, 1px gray border,
 *                     padding 16px 0 16px 32px, margin 0 32px
 *   - .sg_toc:        cream #fefedd, 1px gray border,
 *                     padding 16px 48px 48px, margin 0 0 32px
