/* SINTRA website stylesheet
   Follows the SINTRA brand brief (Design/SINTRA-Brand-Brief.md):
   - Helvetica only (Arial where Helvetica is unavailable). Hierarchy from size and weight alone.
   - Six colours: Sintra Green, Sintra Red, Ink, Grey, Light, Rule grey (+ #CFE0D4 for secondary text on green).
   - Roughly 70% white, 25% green, 5% red. Red is an accent only: rules, numerals, single marks.
   - Green fields carry headings and short lines only, never body copy.
   - The rounded #F2F2F2 card is the repeated motif. Minimum text size 16 px. */
