/* 1.  Tabular header bolding ----------------------------------------- */
/* LaTeXML auto-promotes the first row of a tabular to <th>, which the
   default stylesheet bolds. For Latin squares and layout-only tabulars
   (no caption, not inside a <figure>) that's wrong — the cells are
   data, not headers. Strip the bold by default, then re-apply it only
   inside captioned tables. */

   leaks an inline `font-size:80%` onto matching List-of-Tables entries
   (e.g. 6.2, 8.5, 8.7). PDF renders the LoT uniformly; do the same. */

/* 4.  Latin-square cells -------------------------------------------- */
/* Latin squares come from two source forms:
     (a) raw \begin{tabular}{|c|c|...|} in app2.tex (HTML <table>)
     (b) our \iflatexml \hbox{\begin{tabular}{...}} replacement of the
         \begin{latinsq} macro (rendered as <span class="ltx_tabular">)
   In both forms LaTeXML emits cells with class `ltx_td` (and
   `ltx_border_l/_r/_t/_b` for the border-spec | columns).

   Without help, empty cells collapse to ~0 width, empty rows collapse
   to ~0 height, and digits sit flush against borders. Apply uniform
   sizing to any cell that has at least one of the border classes —
   that selector matches Latin-square cells but also legitimate header
   tables (Table 8.4 etc.). The latter already have content, so
   `min-width` doesn't shrink them; `height` only takes effect when
   the cell would otherwise be smaller. */
