   stroke, so the line is visibly inside the quote block. Left-aligned and unruled it
   read as an orphan: the quote's last line is short (社群。), which opens an L-shaped
   void to its right, and a detached line under that void looked like a stray.

   RIGHT-ALIGNED for the same reason — it fills that void and reads as an attribution
   under a quotation. On narrow screens the line nearly fills the column, so the
   alignment is barely perceptible there and the block just looks centred.

   Luzu and Foshrine are both native-square (zero crop, edge to edge); Guanyin sits in a
   deliberate 神龕 alcove (contain on deep paper, top glow) — no deity is cropped.

   This briefly became a 4:3 contain-everything row, when the Buddhas panel held a
   2.26:1 crop of the hall: cover would have sliced off the outer two of the 四座千佛
   寶塔燈 its caption names, and containing a panorama in a square left it a thin strip
   marooned in empty paper. The centre then supplied a SQUARE hall photograph, which
   removed the reason for the 4:3 window, so this reverted to the original geometry.

   The rule that survived both rounds: a panel source should be square or taller, never
   a panorama. If one arrives, fix the SOURCE — do not reshape the row around it, and do
   not let cover crop a deity to make it fit. */
