/**
 * Theme Name: Simple
 *
 * Distinctive features:
 *  - Prev / next month navigation: text-only `<` `>` arrows with no
 *    background and no border, so they don't read as buttons
 *    (matches the Elegant theme's nav style).
 *  - Weekday header: no background, no border. Plain text only.
 *    The base stylesheet draws a 1px frame on th, plus default
 *    browser borders sometimes appear on the table / thead / tr
 *    edges; we reset all of these aggressively with `!important`
 *    (same approach as the Elegant theme).
 *  - Date cells: keep the base 1px gray frame.
 *  - "Today" cell uses a small accent circle on the date number.
