   Larchmont Bookkeeping — shared stylesheet

   Tokens and shared components for every page. Page-specific rules
   stay in a <style> block on the page that needs them.

   Shape rule:  buttons are pills, cards and photos are 16px.
   Colour rule: one blue does every clickable thing. Mint is the
                included-tick only; the warm gold is the
                text-selection highlight. Neither ever appears
                on a control.
