/* free_calc.css — the phone-first free-calculator surface (T-LITE-3).
   Loaded ONLY on /calculators/* so the marketing pages pay nothing for it.

   The brief, in the owner's words: "the value for a cellphone app would be to
   filter and then open the direct PDF links on the phone." So the design rules
   are not stylistic:

     * ONE column at every width. There is no desktop layout to fall back to,
       because the user is standing up.
     * Every tappable thing is >= 44 px tall, and the two document buttons are
       full-width — they are what the page exists for.
     * The result list starts ABOVE THE FOLD after a search. The form collapses
       to a single line once it has been used.
     * Nothing is truncated. Citations, notices and the search scope go into
       <details>, which is expandable, offline, and needs no JavaScript.
     * No horizontal scroll at 375 px. Long approval numbers wrap; nothing is
       laid out in a table.                                                    */
