/*
 * openSIF
 *
 * A calm white utility page wrapped around one opinionated thing: the ledger.
 * The employee list is a table, not a stack of cards, because the file this
 * tool produces is a table and the row numbers it prints are the row numbers
 * the bank's error report will cite. Amounts are set in tabular figures with
 * the baisa (the three decimals of the rial) held back a step, so decimal
 * points stack down the column and a mistyped 9440.000 is visible at a glance
 * instead of hiding among its neighbours.
 *
 * Two constraints shaped the rest:
 *
 *   RTL is not a skin. Every box uses logical properties - inline-start rather
 *   than left - so the whole page mirrors from one dir attribute. Nothing is
 *   positioned with left/right anywhere in this file.
 *
 *   Arabic has no letter case, so no label may lean on capitalisation to read
 *   as a label. There is no text-transform in this stylesheet; hierarchy comes
 *   from size, weight, colour and space, all of which survive the switch.
 *
 * Validation state is never carried by colour alone: every flag prints a word.
