/* RUNAPP v1.2.0 — dark athletic theme.
   v1.2.0 (2026-09-07): Hidden PBs gained a source column and an
   explanation card (.pb-source, .pb-note) for PBs that come from a race
   certificate rather than the watch.
   v1.1.0 (2026-09-07): Race Calendar gained a Completed section
   (.section-head, .race-stats) and Coach Bru gained the block's
   standing rules (.rule-row). Card values and notes now break inside a
   long unbroken word rather than pushing the page sideways.
   v1.0.1 (2026-07-23): mobile overflow fix — tiles now shrink below
   their content width (min-width:0), tile numbers scale down on narrow
   screens via clamp(), badges wrap, and the page can't scroll
   sideways. Found on Johann's phone right after cutover: the grid's
   third column was pushed off-screen by long content ("244 m/min",
   "days to Linton's Corner Spring Race").
   Signature: race-bib condensed numerals (Barlow Condensed, tabular)
   with a hairline status underline on every tile/card. Status palette
   carried over 1:1 from the Streamlit app so meanings stay learned:
   green #4ade80 good · amber #fbbf24 watch · red #f87171 risk ·
   blue #60a5fa easy · violet #7f77dd coach · route-green #39d98a. */
