/* ---- Tablet and phone ------------------------------------------------
   Selectors below are prefixed with `body` on purpose: a page regenerated by
   an old generator still embeds the legacy style block *after* this file in
   document order, and its phone rules (`.kic-page rt { font-size: 0.5em }`,
   `.kic-page { padding: ... }`) would otherwise win on equal specificity.
   Pages are mostly read on a phone or iPad, so Japanese text steps up as the
   screen gets smaller; furigana keeps a 10px floor (see .kic-page rt above).
   Phone rules also reclaim the three stacked side margins (theme body margin,
   .content padding, .kic-page padding) and tame the shared theme's oversized
   table headers so vocabulary tables fit without sideways scrolling. */
